One-way select flow valve that keeps the straw full of liquid.

The Sip-Tip Valves Package of 12 allow fluid to remain in the straw without flowing back into the cup. Great for individuals who have difficulty generating and maintaining suction. By helping the straw stay full of fluid, this valve reduces the amount of energy needed to bring liquid to the mouth. Valve opening is set for moderate restriction for users who tend to aspirate when taking too much fluid in one swallow. This one-way valve can be trimmed at designated areas to increase the liquid flow, giving the user greater control. Sip Tip Valves are compatible with most brands of disposable flex straws. Each valve is made of medical grade materials that are FDA compliant and contain no lead, phthalates, PVC, BPA or latex. Made in USA. Package of 12.
