This is Tochigi Leather, a high-quality domestic leather. Of course, it's vegetable-tanned nubuck leather using the pit tanning method. This is the normal Tochigi Leather, without saddle or oil processing. Because it's pit-tanned, edge finishing is beautiful, and imprints come out nicely. The aging process is also wonderful, so please use it and enjoy it. It's an easy-to-manage A4 size and a great price, so why not stock up? Thickness is approximately 2.0mm. There may be natural scratches, wrinkles, and small marks from storage. *Red tag is not included.
