These are chomping chopsticks with biting action. Take a bite out of your lunch with MUNCHTIME shark chopsticks. They make every meal jawsome. The shark opens and closes its mouth as you squeeze the easy-to-use, hinged chopsticks. They're perfect for kids (or adults.) who are trying to learn how to use chopsticks. All MUNCHTIME chopsticks are made of durable, food-safe ABS plastic.
