Also, leather that has undergone tannin tanning is called "vegetable-tanned leather." It can take several months to tan, requiring time, effort, and space, but it allows the tannin components to 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 process, and you can enjoy the unique expression of the leather.
