Due to Walpier’s highly regarded method of vegetable tanning, the Buttero leather boasts excellent color with a perfect surface finish and is highly resistant to scratches. This allows manufacturers to utilize the original texture of the leather without the problems normally associated with other vegetable processing.
The black color case of KANN MAX uses Walpier's Buttero leather.
Buttero leather is a leather made by milling the leather to make it soft and natural on the surface. Buttero leather, like other leather used by Walpier, is manufactured from the finest French hides, so the texture is dense, and the surface is smooth.
