KAMUI tips are made of vegetable tanned leather. Vegetable tanned leather is a far superior process in durability and elasticity compared to chrome tanned leather. However, vegetable tanned leather has a tendency to absorb moisture which degrades the performance of the durability and elasticity.
KAMUI introduced a special treatment in the tanning process to make the KAMUI leather humidity resistant. This specially treated leather maintains the elasticity and the durability of KAMUI tips in all seasons and even in high humid environments.
