ARK’s Sip-Tip with Select-Flow Valve

The Sip-Tip® makes drinking easier for individuals who have difficulty generating and maintaining suction.  Simply cover the vent hole with your finger and press down several times until the liquid reaches the desired height. The Select-Flow Valve will keep the straw full of fluid, thereby reducing the air ingested and the effort required for each sip.
