Kamui ® Laminated Leather Tips. 9 layers of 100% hand selected pig skin. 4 types of hardness available in the natural color- Soft, Medium Soft, Medium, and Hard. "New" BLACK Kamui tips available Super Soft, Soft, Medium, and Hard. Imported from Japan, the Kamui layered tip consists of 100% pig skin leather. With its unique production process, the tip maintains high porosity in the pig skin, allowing the Kamui tip to grip onto chalk better. This means more chalk and more control. The Black Kamui Tips are more durable and play better in humid conditions, and are more resistant to damage from moisture.
