Reference Guide
The 2026 Leather Glossary
Every grade, finish, and tanning method used in luxury handbags — with field tests you can perform in any store. The reference behind every Duplixo bag audit.
Leather Grades
Quality tier — determines durability, patina, and price ceiling.
Full-Grain Leather
GradeThe entire outer surface of the hide is preserved — natural marks, grain variation, and all. It is the strongest, most durable, and most expensive leather. It develops a patina over time (darkens and tightens with use). Every investment-grade luxury bag uses full-grain.
Field Test
No uniformity. Look for subtle variation in grain pattern across the surface. If every square centimetre looks identical, it is corrected-grain.
Used in: Hermès Birkin (Togo, Clemence), Bottega Veneta, The Row, Loro Piana
Top-Grain (Corrected-Grain)
GradeThe outermost layer of the hide is sanded to remove natural blemishes, then stamped with an artificial grain pattern and coated. It looks perfect immediately but cannot develop a patina. The coating typically delaminates after 3–5 years.
Field Test
Perfect, uniform grain under 10× magnification. The surface feels slightly plastic. Running your fingernail across the surface leaves no mark (the coating is too hard).
Used in: Most luxury brands for entry-level lines and accessories. Many mid-market handbag brands.
Split Leather / Genuine Leather
GradeThe lower layers of the hide after the grain layer has been separated. The weakest leather grade. Often used in bookbinding and shoe linings. When sold as handbag material, it is typically coated heavily or bonded. 'Genuine Leather' on a label = the lowest quality grade while still technically being leather.
Field Test
Spongy, slightly fibrous texture. Does not spring back cleanly when pressed. Often has a faint chemical smell. Edges may show a fibrous cross-section.
Used in: Fast fashion handbags, budget accessories, some mid-market branded linings.
Finishes & Surface Treatments
Applied to full-grain or top-grain leather. Determines appearance, texture, and care requirements.
Togo
FinishHermès's signature pebbled calfskin. Fine circular grain, supple and scratch-resistant. The pebbling is natural — achieved through a tumbling process. More resistant to water spots than smooth leathers. Used on Birkin and Kelly.
Field Test
Fine, consistent circular grain. Presses back easily. Scratch resistant (run a fingernail — grain bounces back). Slightly lighter than Clemence.
Used in: Hermès Birkin, Hermès Kelly
Clemence
FinishA heavier, slightly more relaxed version of Togo from adult bull hides. Larger grain, softer drape, slightly more prone to slouching over time. Often used on larger Birkin sizes where the additional weight provides structural support.
Field Test
Larger grain than Togo, visibly softer when pressed. Heavier hand feel at equivalent size. Grain is slightly irregular compared to Togo's consistent circles.
Used in: Hermès Birkin (larger sizes), Hermès Evelyne
Epsom
FinishHermès's most structured leather. Heavily embossed with a crosshatch pattern and stiffened. Holds its shape extremely well, highly resistant to scratches, does not slouch. The most distinctive Hermès finish visually — the grid pattern is immediately recognisable.
Field Test
Rigid, structured. The crosshatch grid is deeply embossed and uniform. Does not compress when pressed. Lightest weight of the major Hermès leathers.
Used in: Hermès Constance, Hermès Roulis, Hermès Kelly (some colourways)
Box Calf
FinishThe most demanding Hermès leather: smooth, high-gloss calfskin with zero grain. Develops the most dramatic patina of any luxury leather — scratches turn into a silver-tone burnishing that defines the bag's character over decades. Requires the most care and scratches easily when new.
Field Test
Mirror-smooth surface with no visible grain. High gloss without coating (the shine comes from the polishing process). Scratches visibly — run a fingernail lightly and observe. The scratch will burnish over time.
Used in: Hermès Kelly (vintage and special order), Hermès Constance (limited runs)
Saffiano
FinishA cross-hatch embossed pattern applied to calfskin (or occasionally other hides), then coated with a wax finish. Created by Mario Prada. Extremely scratch-resistant, water-repellent, and maintains a uniform appearance indefinitely. Does not patina. The anti-ageing leather — looks identical in year 10 as year 1.
Field Test
Diagonal crosshatch pattern, uniform. Waxy surface feels slightly different from natural leather. Water beads and rolls off. Scratch-resistant: run a key across the surface — no mark. Edges show the applied finish as a thin film layer under magnification.
Used in: Prada (signature), Longchamp, Kate Spade, many mid-tier brands
Nubuck
FinishFull-grain leather buffed on the outer surface to create a fine, velvet-like nap. Unlike suede (which is split leather, buffed on the inner surface), nubuck retains the strength of full-grain leather with a tactile, matte surface. Water-sensitive — requires a nano-protector pre-treatment.
Field Test
Velvety, directional nap. Running your finger one direction lightens the tone; reverse direction darkens it. Unlike suede, does not feel spongy — the underlying structure is firm.
Used in: Loro Piana (shoes and accessories), some Brunello Cucinelli pieces, Arket
Vachetta
FinishUntreated, undyed natural full-grain leather used by Louis Vuitton for handles and trim. Starts as a pale cream, darkens dramatically to honey and eventually caramel with sun exposure and handling. The most dramatic patina of any commercial leather finish.
Field Test
Pale, almost white. No coating, no dye. Water absorbs immediately and leaves a dark mark (which dries out over 24–48 hours). Older vachetta is darker and visibly different from new — patina is the intended end state.
Used in: Louis Vuitton (handles, trim, zipper pulls across the Monogram and Damier lines)
Tanning Methods
The chemical process that converts raw hide into leather. The single most important quality indicator.
Vegetable Tanning
TanningThe oldest method: hides are immersed in natural tannins (oak bark, chestnut, quebracho) over 4–6 weeks. Produces firm, dense leather with excellent patina development. The gold standard for saddle leather, belts, and investment handbags. Environmentally lower-impact than chrome.
Field Test
The Water Drop Test: place a single drop of water on the surface. Vegetable-tanned leather absorbs it within 30–60 seconds, darkening slightly. Chrome-tanned repels water. This test distinguishes the two tanning methods without any equipment.
Used in: Hermès, Bottega Veneta, The Row, high-grade artisan bags
Chrome Tanning
TanningThe dominant industrial method: hides processed in chromium salts over 1–2 days. Produces supple, uniform leather with consistent colour. Does not develop a patina (the chrome locks the leather structure). Much faster and cheaper than vegetable tanning. Most leather globally is chrome-tanned.
Field Test
Water bead or very slow absorption. Cut edge (seam) is bluish-grey inside — the 'wet-blue' signature of chrome tanning. Slightly more uniform appearance than vegetable-tanned.
Used in: Most commercial leather globally. Coach, Michael Kors, majority of mid-market bags.
Aldehyde Tanning (Chrome-Free)
TanningUses glutaraldehyde or oxazolidine compounds instead of chromium. Produces a wash-resistant, chrome-free leather with good suppleness. Required for 'chrome-free' certification. Used in automotive leather and premium fashion where chrome VI sensitivity is a concern.
Field Test
Visually similar to chrome-tanned. The wet-blue cross-section is absent — edge appears cream to light brown. Water absorption is between vegetable and chrome.
Used in: Some Arket, Sézane, and premium mid-market brands marketing 'chrome-free' credentials.
