This leather has a bony yet comfortable look, with scratches and grain to give it an impactful look.
The leather is tanned in Japan by soaking raw horsehide in a pit tank.
The leather is fully tanned in a pit tank for about 3 months, taking advantage of the characteristic of horsehide that has many scratches.
The leather is then turned on a taiko while being heated and shrunk to half its normal size (from 2m to 1m) to give it an impactful look with its scratches and graininess.
This leather is full tannin, and has a bony appearance, but by adding a lot of oil, it has elasticity and suppleness, and is comfortable to wear.
