Nuby's 3-Stage Training Cup Set helps little ones learn to leave the bottle behind and take those first steps toward drinking like a big kid. The 3-Stage Training Cup Set comes complete with a Free-Flow spout top and a No-Spill Touch-Flo straw top, letting your child seamlessly transition to the next step of sipping when they're ready. When your little one has the hang of self-led sipping, remove the top and use the training cup as an open cup! The cup walls are angled, creating a steady flow and making your child's sips natural, easy, and safe. Featuring handles on each side, this 100% silicone cup set is gentle on gums and teeth and features an Easy Grip, non-slip design that is easy for little hands to grasp and hold. The 3-Stage Training Cup Set holds 4 ounces (120 mL) of liquid, perfect for beginners practicing open-cup sipping for the first time. Get ready for steady big kid sipping with Nuby's 3-Stage Training Cup Set!
