Also, leather that has been tanned with tannin is called "nume leather." It can take several months to tan, requiring time, effort, and space, but instead, the tannin components can be slowly absorbed into the leather without burdening it. As a result, it is durable and less likely to tear, and its softness increases with age, and its texture changes. The more you use it, the more you can enjoy the aging (change over time), and you can enjoy the unique expression of the leather.
