A set of chopsticks (18cm) and a chopstick case that prevents "clattering" sounds. Antibacterial specification with silver ion. The case opens sideways, allowing for slim storage of chopsticks!

The soundproof cushion firmly holds the chopsticks, preventing them from shaking up, down, left, and right, thus reducing noise! Dishwasher safe.
