These replacement straws will fit most Nûby™ Sport Sippers. They are designed to make the transition from spout to straw drinking easier. They feature a No-Spill™ Touch-Flo™ valve that opens instantly with a small amount of pressure, making it easy to drink from. When the pressure is released, the straw 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! *Fits most Nûby™ Sport Sippers*
