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 to hear "clattering" sounds. The soundproof cushion firmly holds the chopsticks, preventing them from shaking up, down, left, and right, thus reducing noise. Dishwasher safe.
