ChiaoGoo bamboo hooks are made from Chinese Moso bamboo which is the largest and strongest bamboo from over 1,000 different species; dark patina needles go through an additional thermal process to obtain the darker color (no dyes or paints are used attain this richer color). Points are handcrafted by highly skilled craftsmen. The tapered hook features a precisely placed hold for comfort in the hand. Size is permanently laser etched on each item for added convenience and easy storage.
