The perfect size for little hands! Our versatile silicone training cups can be used as an open cup that is soft on little mouths or with a lid + straw for those toddlers still learning to drink by themselves. These sippy cups are more than just design, they also help get motor benefits relating to on-lip seal, cheek strength and much more. These cups are intended to teach your baby/toddler to drink from a straw so they are not spill-proof! They are perfect for little ones just starting out and can hold up to 6 ounces of their favorite drink or smoothie. The cup, lid, and straw are made with 100% recyclable, food-grade silicone it is BPA and phthalate-free, is reusable and pretty much unbreakable. Dishwasher safe, a breeze to keep clean and reuse.
