These universal straw tops turn any cup into a no-spill cup! The unique design of these tops allows them to stretch over and grip the top of any cup while air suction helps keep the top in place. Set of 3 tops and 1 silicone straw. Made from 100% silicone. Dishwasher and microwave safe.
PLEASE NOTE - While the Siliskin Straw Tops have a super stretch, they can still tear if not used properly. Please use with care when taking on and off cups.
