Visual effect - cute and delicious cookie shape. The product surface design is varied, so baby can feel different when chewing, biting, grasping and holding. The cloth lanyard allows baby to put in the plastic ring by itself, training baby's logical thinking and hand-eye coordination skills. The main part has three sterilization methods (boiling sterilization, liquid sterilization, microwave sterilization), so whether baby wants to bite, touch or lick, mom can rest assured! Please wipe the plastic ring with warm water to clean it.
