Size 7, Width 5mm Works by my woodworker father. Yakusugi cedar endures for over a thousand years in harsh natural conditions, making tremendous efforts to survive. It grows in soil with very few nutrients, resulting in extremely narrow annual rings. To withstand long-term decay, it stores oil within itself. This oil is what gives the works their deep color. I hope to share in the longevity of Yakusugi cedar. Yakusugi cedar grows on Yakushima Island, a granite island with poor nutrients. Its growth is slow, and its grain is tight. Due to high rainfall and humidity, it contains a lot of resin, making it resistant to decay. Therefore, the trees are said to have long lifespans. Those that grow naturally in mountainous areas above 500m and are over 1000 years old are called Yakusugi cedar. Currently, new logging is prohibited. It is a rare and auspicious wood, also said to ward off bad luck ("yaku ga sugiru"). Coated with impregnating urethane coating (Kikata Ace), so it's safe even if you sweat. It meets food sanitation standards. Please care for it with a soft silk or cotton cloth. It is not as hard as a metal ring, so please handle it with care during use.
