A set of chopsticks (18cm) and a chopstick case that prevents "clattering" sounds. The case opens sideways and can store chopsticks in a slim manner. The case has a soundproof cushion, making it difficult for "clattering" sounds to occur. The soundproof cushion firmly holds the chopsticks, preventing them from shaking up, down, left, and right, thus reducing noise. Dishwasher safe.
