1. Natural, also known as aniline leather:
It has open pores and can only be dyed with aniline dyes (organic compound), no foot imperfections can be covered.
Some ranchers even look for regions where there are few or no insects to protect their animals from scars.
It is for this reason that this leather is impeccable, hence its excellent quality.
2. Lightly pigmented:
As in the case of natural nappa leather, the lightly pigmented nappa leather is dyed with soluble dyes mixed with pigments, making it authentic in color and rubbing; it also shows an even appearance.
Both nappa leathers mentioned are vapor permeable.
3. Pigmented:
In pigmented nappa leather the color is fixed on the surface, thus, it is less breathable and less delicate, but easier to clean.
4. Polished:
In this case, the grain side of the leather is polished, achieving a smooth surface to which a layer of color is applied; the natural characteristics are gradually lost.
Because of its softness, durability, and high-end appearance, nappa leather is especially used in the manufacture of handbags, gloves, shoes and other accessories.
