Tochigi Leather, Blue, Thickness 2.5-2.8mm This leather is tanned with vegetable tannins. It's infused with oil, giving it suppleness, durability, and a moist texture. The back is heat-treated. It costs about 250 yen per decimeter. We cut A4 size pieces from a half-cut hide, selecting the parts with the fewest wrinkles. The leather's appearance varies depending on where it's cut, so please let me know if you have any preferences. Because it's cut by an amateur, the edges may not be perfectly clean, so we'll cut it slightly larger. There may be small scratches, but these are natural markings inherent to genuine leather. Ideal for mouse pads, coasters, and a wide range of leathercraft projects due to its thickness and flexibility. Blue leather will change color quickly due to UV exposure, eventually developing a deep teal hue.
