ARK's Premium One-Way Valve (formerly called Vangi Valve)

Price: €25.00
Ex VAT: €20.33
Product Code: ARK050
Availability: In Stock

ARK's Premium One-Way Valve makes drinking easier by controlling the direction of fluid - fluid flows up into the straw, but does not empty back into the cup.  Because fluid always stays at the top of the straw, less effort is required for each sip.  The valve is easy to take apart, clean, and put back together, which is especially important if you use thick fluids (many other valves clog and cannot be cleaned out).  This product is highly recommended for individuals with oral motor difficulties, a weak suck, or problems generating and maintaining suction.

This product is made in the USA out of medical grade stainless steel that will not rust.

All parts can be boiled in water to ensure sanitary conditions.

Sold individually.

Compatible with most regular drinking straws.

Measures just over 2 inches in length.

Included in the package is an extra stainless steel ball and washer.

Caution: choking hazard; please supervise at all times.
