Veg-tanning is the most common leather. Its name comes from the bark of plants and trees in the process of tanning. These plants combine to create hard but natural colored leather. The light color of vegetable tanning will not be retained for a long time, and will become soft and deep with time, showing a unique luster. It should be noted that Veg-tanning cannot be soaked in water, otherwise it will shrink and become brittle after drying.
