Nuby - No-spill Flip-it - Replacement Kit

These Straws serve as  replacements for the No-SPill Flip-it's by Nuby. 

The new soft sipper straw is gentle to child's tender gums and emerging teeth.  The silicone drinking straw is made from a soft silicone and is uniquely designed to help prevent drips and spills. 

With a pressure sensitive valve feature safely built right into the straw, fluid only flows out of the straw with sucking action of child.
