Allows liquid to flow only up the straw.

These straws have one-way valves in them that make drinking easier for individuals with problems generating and maintaining suction.

The One-Way Drinking Straw features a one way valve that allows liquid to flow only up the straw. Liquid will not flow down this one way straw after lips are removed.

The one way valve also eliminates sucking air from an empty straw. Each package contains 10 - 7 inch straws. Ideal for persons with weak oral musculature or difficulty swallowing.
