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 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 it is characterized by increasing softness and changing texture over time. You can enjoy aging (changes over time) the more you use it, and enjoy the unique expression of the leather.
