All are made from Hinoki, Japanese Cypress (light weight, germ-and -odor free) from Tosa-ryu in Shimanto.
Tosa-ryu products are made from aromatic Japanese cypress which is a natural bi-product of the forest thinning process. Hinoki wood is prized in Japan for its appealing, bracing scent. The natural resin content of Hinoki prevents mold and mildew and resists bacteria and absorption of food odors. Hinoki products should be washed by hands. Excess resin may be removed with hot water.
