It is leather tanned using tannin, a plant-derived substance. The tanning process tightens the leather fibers, making it a very durable material. However, with each use, it becomes more familiar to the hand and smoother, and the color and luster increase, changing the appearance of the leather. Enjoy the aging process that comes with use.
