Nuby’s Cool Sipper keeps drinks cool while preventing spills and leaks! The cup’s soft rim spout features a Vari-Flo valve that helps regulate fluid intake as children drink. As children sip on the spout, the valve opens and allows liquid through. When sipping ceases, the valve closes, ensuring a leak-resistant cup. With available replacement kits for the silicone soft rim spout, parents can have a backup while cleaning. The 2 pack of replacement spouts enables parents to enjoy the longevity that Nuby products provide for their families.

• 2 pack replacement spouts for Clik-it Cool Sipper sippy cups (*not all Cool Sipper cups are compatible - ensure your cup makes a 'click' sound when securing the lid for compatibility*)
• Replacement spouts suitable for children 18+ months
• Soft silicone rim spout is designed to be gentle on gums and teeth
• The spouts are dishwasher safe, making them easy to clean
