The Shiosai Blue Antibacterial chopsticks feature silver in the finish to perhaps provide a level of protection. Besides the wonderfully elegant mother of pearl surrounded by blue shimmer on dark wood, the chopsticks are also dishwasher safe for easy care. The chopsticks have a base of Jabon wood (Anthocephalus cadamba), harvested in Indonesia. They have a Polyester Urethane protective finish. Chopsticks are 8.875 inches long with lightly textured tips. Made in Obama, Japan on the shores of Wakasa Bay.
