Using this Stelton Pingo children's tableware set is super easy. Just serve your child's favorite food on the flat or deep plate, and pour a drink into the cup. When your little one is done eating, simply wash the pieces with mild dish soap and warm water. Avoid using abrasive sponges as they may scratch the melamine surface. Store the set in a dry place away from direct sunlight to keep the penguin design looking vibrant. If for any reason you're not satisfied, remember it's covered by our 30 - day return policy.
