The Cool Sipper™ Replacement Top is designed to make the transition to open drinking easier. Like many of our silicone spouts and straws, this Cool Sipper™ Replacement Top features a No-Spill™ Touch-Flo™ valve that opens instantly with a small amount of pressure, making it easy and simple to drink from. When the pressure is released, the spout closes ensuring a leak resistant cup. This unique valve originated on Nûby™ cups and is endorsed by pediatric dentists all over the world because it encourages natural drinking and oral development. And since it's from Nûby™, you can be assured that it is BPA Free!
