No more worrying over spills and leaks! Nubys Clik-It Soft Spout Trainer Cups lid clicks when twisted into place, so parents know its securely attached to the cup base. Nubys 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 (and dropping) their drinks. Thats 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.
