Re-Play's Straw cups are perfect for kids on the go. They have a screw-on lid with a circular opening for the bendy neck straw. The shape of the cup, thinner at the base than at the top, makes it easy for small hands to hold and the surface is textured, as with all the Re-Play products, to prevent the product from slipping. Not only are they better for your child, they are better for the environment.
