These One Way Flextendable Drinking Straws feature a special one-way valve that holds liquid in the body of the straw.
This means that when suction is released, the liquid does not drain back into the glass.
It is therefore useful for people who struggle to maintain suction during drinking.
The valve also prevents air pockets being ingested and causing uncomfortable bloating.
Each pack of One Way Flextendable Drinking Straws contains 15 straws in various colours.
Length: 28 cm extending to 33 cm (11 to 13 inches).
