Zumoe's designer mouthguard and retainer cases are used by athlete's for their mouth guards or retainers. However Zumoe's cases can store many other items; mothers love the cases to store pacifiers, kids love to store jewelry, money, candy or other items and attach the cases to their knapsacks or lunch boxes. These cute designs fit perfectly in a bedroom or bathroom, replacing the drab retainer case from the dentist or orthodontist. Zumoe cases are also great gifts.
