When faced with a leather bag or wallet, it's hard to know what's really under the surface. The terminology used for leather is often vague, sometimes deliberately so, and two pieces that look similar to the naked eye can have a ten-year difference in lifespan. Here's how to tell the difference.
Full-grain leather: the hide in its closest-to-natural state
Full-grain is the outermost layer of the animal's skin, the one where the hair grew. It is not sanded or artificially corrected: the natural grain remains visible, with its small irregularities that prove it is a living, un reconstituted material.
This layer is also the densest in collagen fibers, which makes it naturally resistant to wear and tear. It is what develops a patina over time: it marks, darkens slightly, polishes with use, and gains character instead of degrading. A full-grain bag worn for ten years does not have the same leather as when it left the workshop – it has a story.
Split leather: what remains once the grain has been removed
Split leather is the lower part of the hide, obtained after separating the grain for other uses. This layer is more fibrous, less dense, and, crucially, lacks the natural protective surface. When raw, it is fragile and absorbs water and stains easily.
To be saleable, it is almost always covered with a layer of pigment or a plastic film that imitates a regular leather grain — hence perfectly smooth and uniform surfaces, without the slightest irregularity. This is often a good sign... of a bad sign: "too perfect" leather usually hides a surface treatment that masks the real material underneath. This type of leather does not develop a patina; it flakes.
How to tell the difference in store or from a photo
Some simple guidelines:
- The grain: on full-grain leather, you can see slight irregularities, pores, sometimes small natural marks. On coated split leather, the texture is artificially regular, almost printed.
- The feel: full-grain leather has a supple but firm hand, with a slight warmth to the touch. Coated split leather is often colder and more plastic.
- The edge: if you can see the edge of the leather (on a belt, for example), full-grain shows a dense fibrous structure throughout its thickness. Coated split leather reveals a surface layer distinctly different from the rest.
- The price: a genuine full-grain bag has a higher raw material cost — be wary of a price that doesn't match the promise.
Why MRLM works exclusively with full-grain leather
At MRLM, every piece — bags, belts, cases — is crafted from Spanish vegetable-tanned full-grain leather, with no surface alterations that would mask the material. This choice requires more rigor in selecting hides, but it is also the only way to offer an object that ages with its owner rather than degrading over time.
