the leather
we use
A complete guide to natural leather — what makes it different, how we choose it, and how to care for it so it lasts a lifetime.
not all leather
is the same
A single hide is split horizontally — first into two halves, then refined further. Each section becomes a different grade of leather. Tap any grade below to see where it sits in the hide and what it's actually used for.
Full-Grain
The upper half of the hide, with the very top surface left completely intact. Nothing sanded, nothing buffed away. The strongest, densest fibres in the entire skin remain in place — along with the natural marks, scars, and grain pattern that make every piece unique.
This is the only grade of leather that develops a true patina. It is the most expensive, the hardest to source, and the most demanding to work with — because the tannery cannot hide a single imperfection.
The classic Hermès Birkin and Kelly bags. Louis Vuitton's premium leather goods. Hand-stitched English saddles. Bespoke shoemakers like John Lobb and Edward Green. Heritage leather workshops worldwide. And every single piece we make.
Top-Grain
Here is where it gets confusing: technically, full-grain is top-grain — both come from the upper half of the hide. The difference is what happens next. Top-grain leather (as commonly sold) is the same upper-half cut, but with the natural surface sanded down to remove imperfections, then coated with a finish to imitate consistency.
Looks uniform on day one. Feels almost the same. The problem: by sanding off the natural surface, you also remove the strongest, densest fibres — and the part that develops a patina. Top-grain leather will wear and crack instead of aging gracefully.
Most mid-range department store wallets and bags. Coach (most lines), Michael Kors, Kate Spade, Tory Burch. Mass-market designer leather goods that need to look identical at scale. Premium-priced but not premium-grade.
Genuine / Split
"Genuine leather" is one of the most misleading labels in the industry. It refers to the entire lower half of the hide — what's left after the top half (full-grain / top-grain) has been split off. The lower half lacks the dense fibres of the upper half. Soft, weaker, and prone to falling apart.
Despite the name, genuine leather is the lowest grade of real leather. It is weak, prone to cracking, and will not last. If a product proudly says "genuine leather" — that is the entire claim it can make.
Fast-fashion accessories at H&M, Zara, Primark. Cheap belts and wallets sold at airport gift shops. Shoe linings. Cheap office chairs marketed as "genuine leather." Usually anything with a price that seems too good to be true — because it is.
Bonded
Bonded leather is the leather equivalent of particleboard. Leftover scraps and dust are ground up, mixed with adhesives, and pressed into sheets. The surface is then printed or coated to look like real leather.
It contains as little as 10% actual leather fibres. It will peel, crack, and disintegrate within a year or two.
Cheap sofas marketed as "leather furniture" at warehouse outlets. Bargain-bin office chairs. Knock-off bags sold on street corners. Decorative book covers. Garbage, essentially — designed to look like leather just long enough for the warranty to expire.
We only use full-grain leather — every piece, every product, no exceptions. It costs more, it takes more skill to work with, and it is the only material that earns the patina we promise. If a leather good is going to last thirty years, the layer it is cut from has to be capable of lasting thirty years.
the leathers
we use
Five full-grain, vegetable-tanned leathers from heritage tanning regions in Tuscany and Alcanena. Each chosen for what it does best.
Badalassi Carlo Waxy
Vegetable-tanned in wooden drums in Tuscany using a proprietary blend of waxes, oils, and animal fats. The waxy finish is what makes this leather instantly recognisable — a distinctive matte depth that lightens at folds and pressure points, gradually pulling back over time to reveal richer tones beneath.
Conceria Badalassi Carlo has been tanning leather in Tuscany for over fifty years. Members of the Vera Pelle Italiana Conciata al Vegetale consortium — one of only nineteen tanneries certified to produce true Tuscan vegetable-tanned leather.
At 2mm, the waxy is our thickest wallet leather — substantial, structural, and dramatic in patina. Used for our signature snap wallet where the leather wraps as a single panel and needs to hold its form without stitching.
Buttero
Buttero is produced by Conceria Walpier in Tuscany. A smooth, full-grain vegetable-tanned leather with a semi-glossy aniline finish that lets the natural grain show through. Medium-firm in temper — it holds its shape, takes colour vibrantly, and develops a deep lustrous patina with daily use.
Resilient, scratch-resistant, and consistent. The leather of choice for fine leather goods makers across Italy and beyond. Where other leathers are characterful, Buttero is precise.
At 1.4mm, Buttero is thin enough to layer beautifully — fold it, stitch it, stack panels of it inside a pocket-sized wallet without bulk. Its smooth finish takes our edge burnishing cleanly. Our default leather for the bifold and passport pieces.
Pueblo
Pueblo is unmistakable. Made by Badalassi Carlo using the traditional Vacchetta method on hides from cows over two years old, then deliberately finished with a rough, fibrous surface that resembles fine washi paper — completely matte, almost suede-like to the touch.
With use, the surface fibres flatten, gloss develops rapidly, and the colour deepens dramatically. The transformation is faster and more visible than any other leather we work with. Available in selected colourways.
Pueblo's fibrous surface gives a piece visual depth and tactile character that smooth leathers cannot match. Used on our larger structured pieces — the bifold and passport cover — where there is enough surface area for the texture to make a real visual impact.
Rocky
Rocky is Walpier's belt-grade leather — full-grain, vegetable-tanned, and cut from the tightest, densest sections of the hide. Where Buttero is refined and structural, Rocky is built for tension. It holds a body's weight for years without stretching, deforming, or losing shape.
At 3–4mm, more than twice the thickness of our wallet leathers. The finish is more natural, the temper firmer. Designed to age into something heavier, deeper, and more characterful than it begins.
A belt is the only leather good that performs under continuous tension. It needs tensile strength a wallet leather cannot provide. Rocky's thickness and density mean it holds its shape for decades — and the cut from the tightest grain section ensures it ages without cracking at the buckle holes.
Curtumes Angelinos
Alcanena is a small town in central Portugal known as the "Land of Leather." Its tanning tradition stretches back over five hundred years, and in 1786 it was awarded the first Royal Charter for an industrial tannery in Portugal. Today, only three tanneries in Alcanena still tan exclusively with vegetable tannins.
Curtumes Angelinos is one of them — founded in 1930, still run by the founding family. Their leather is full-grain, slightly firmer than its Tuscan counterparts, with a more restrained patina that develops gradually over years. Available in selected colourways.
Angelinos shares Buttero's wallet-friendly thickness with a slightly firmer hand and a more restrained patina. Offered on the bifold and passport cover for clients who want something genuinely uncommon — a leather with the heritage of a five-century-old tanning tradition.
what to know
about natural leather
Natural full-grain vegetable-tanned leather behaves like the natural material it is — not a plastic-coated mass-market product. Here is what that means in practice.
Avoid water entirely
Especially in the first six to twelve months. Vegetable-tanned leather absorbs water deeply — far more than chrome-tanned. Water marks, dark stains, and warping are very difficult to reverse. The leather earns water resistance over time as it patinas. Until then: keep it dry.
It will mark and scratch
This is not damage — it is the leather doing exactly what it is supposed to do. Scratches, marks, and small impressions are absorbed into the patina over time and become part of the piece's character. Use it. Carry it. Let it record the life it is helping you live.
Colour will deepen and shift
All vegetable-tanned leather darkens over time — through sun exposure, hand oils, and atmospheric oxidation. A pale Buttero will warm to honey browns within months. Pueblo will deepen dramatically. The colour you receive on day one is the starting point, not the finish.
Heat is the real enemy
Direct sunlight, hot car interiors, radiators, and hairdryers will dry out the leather faster than anything else. Once it dries out, it cracks. Store it in normal indoor conditions. If it gets wet, never dry it with heat.
Dye transfer can happen
In the first weeks of use, deeply dyed colours — especially navy, burgundy, and royal blue — can transfer faintly onto light fabrics through friction. This settles within a few weeks of carrying. Avoid pairing brand-new dark wallets with white linen until the dye has stabilised.
Each piece is unique
Natural full-grain leather carries the marks of the animal — fine veins, slight grain variations, healed scars, range marks. We select hides carefully but we do not airbrush or coat over these. Two pieces ordered in the same colour will not be identical. They are not supposed to be.
how to care
for your leather
Tap any section to expand. Read once, return whenever you need it.
Vegetable-tanned full-grain leather is the easiest leather in the world to care for — it asks for very little and rewards you for decades. The mistakes people make are almost always over-conditioning, getting it wet, or applying the wrong product.
Carry it daily
The single best thing you can do for natural leather is use it. Daily handling transfers a fine layer of skin oils to the surface, which is exactly what the leather wants. A wallet carried every day will always outlast one kept in a drawer.
Store it sensibly
When not in use, keep it in a dust bag or drawer at normal room temperature. Out of direct sunlight. Away from radiators and hot windowsills. No special humidity-controlled cases needed.
Brush occasionally
Once every couple of weeks, give the leather a quick brush with a soft horsehair brush to remove dust and lift the surface. Takes ten seconds. Makes a noticeable difference to how the leather ages.
Don't overstuff
Wallets are designed for what they hold. Stuffing a card holder with twelve cards when it's designed for five will permanently stretch the leather and weaken the stitching.
Do nothing
New vegetable-tanned leather already contains all the oils and waxes it needs. Conditioning too early will darken it unnaturally and interfere with the patina. Just carry it. Let it break in.
Light conditioning
Once the leather feels noticeably drier, apply a small amount of high-quality vegetable-tanned leather cream. Apply with a soft cotton cloth in small circular motions. Let it absorb for 15 minutes. Buff off excess.
Saphir Vegetable Cream
Twice yearly
After the first year, condition every six months. Saphir Renovateur is the industry standard — used by shoemakers and luxury houses worldwide. A pea-sized amount is enough for a wallet.
Saphir Renovateur
Less is more
The single biggest mistake is using too much product. A pea-sized amount covers an entire wallet. If the leather feels greasy after application, you used too much.
Never apply cream or conditioner to Pueblo leather. Its signature fibrous surface is its defining feature — applying oils flattens those fibres permanently and destroys the texture. Pueblo conditions itself through hand contact and use.
Blot, do not rub
Use a soft, clean, dry cotton cloth. Press gently to absorb the water. Do not rub — rubbing pushes water deeper into the leather and can lift the surface fibres.
Air dry slowly
Leave the piece flat in a cool, dry, well-ventilated room. Stuff a wallet lightly with paper towels to help it hold its shape. This takes 24–48 hours.
Never use heat
No hairdryers, no radiators, no direct sunlight, no ovens. Heat dries leather from the outside in, leaving the inner fibres wet and the surface brittle. The leather will crack — sometimes immediately, sometimes weeks later.
Condition once dry
After it is fully dry — and only then — apply a light coat of Renovateur to restore some of the oils that the water leached out. This step is what brings the leather back to life.
If the piece has been heavily soaked or stained, get in touch with us before attempting deep restoration. Leather that has been mishandled after getting wet is much harder to recover than leather that arrives in its still-wet state.
We use Saphir Médaille d'Or in our own workshop. It has been the standard for high-end leather care since 1925 and remains the choice of bespoke shoemakers and luxury leather houses worldwide.
- Saphir Médaille d'Or Renovateur — The all-purpose conditioner. Cleans, nourishes, restores. The single most useful product to own.
- Saphir Vegetable Tanned Leather Cream — Specifically formulated for veg-tan. Lighter than Renovateur. Ideal for the first conditioning.
- Soft horsehair brush — For dust removal and light buffing.
- Soft cotton cloths — Old plain cotton T-shirts work perfectly. Avoid microfibre.
- Mink oil & neatsfoot oil — Too aggressive for fine vegetable-tanned leather. Will over-darken and over-soften.
- Shoe polish & wax — Surface coatings. They block the patina process.
- Saddle soap — Designed for thick saddle leather. Too harsh for a 1.4mm wallet.
- Supermarket "leather conditioners" — Almost always silicone-based. Forms a film, blocks the leather, very hard to undo.
every piece
ages differently
Vegetable-tanned full-grain leather responds to its owner, records its history, and improves with time. The leather you receive on day one is not the leather you will carry in ten years. That is the whole point.
