This is Tochigi Leather, a high-quality domestic leather. Of course, it's the flesh side of vegetable-tanned nude leather, tanned in a pit. It's normal Tochigi Leather, without saddle or oil processing. Because it's pit-tanned, edge finishing is beautiful, and imprints come out nicely. However, there are also disadvantages, such as lower durability compared to leather with the grain side. There are various uses, such as for core materials, practice for creating prototypes, leather strops, and stacked leather. Those who buy in half-cuts often have leftovers, but those who buy cut leather might find themselves short. Flesh leather is often sold in half-cuts, but it's often more than needed, so we've cut it to A4 size. It's an affordable price in an easy-to-manage A4 size, so how about stocking up? Thickness is approximately 1.0-1.5mm. There may be natural scratches, wrinkles, and small scratches from storage.
