No more worrying over spills and leaks! Nuby’s Clik-It Soft Spout Trainer Cup's lid "clicks" when twisted into place, so parents know it’s securely attached to the cup base. Nuby’s Clik-It Soft Spout Trainer Cup has a soft silicone spout designed to prevent drips, spills, and messes. Active little ones are animated, even while holding (or dropping) their drinks. That’s why Nuby designed a cup spout with a pressure-sensitive TOUCH-FLO valve. As children sip on the spout, the TOUCH-FLO valve opens to allow liquid through. When sipping stops, the TOUCH-FLO valve closes, ensuring a leak-resistant cup. The 2-handle design makes it easy for little hands to grasp and hold the cup. Whether your little one sits still or keeps moving and shaking while sipping, Nuby has you covered.
