Cups and tumblers are designed with permanent adhesive vinyl. We recommend using a soft sponge to clean exterior of the cup to prevent vinyl from peeling. Our cups and tumblers should not be placed in the freezer, dishwasher or the microwave. Each one comes with a matching color straw. Tumblers are insulated, keeping your drink fresh for hours. Do not allow children to play with cups. Acrylic cups can break if dropped. Handle with care to extend usage. *Important: Cups and tumblers are sold individually. There are multiple pictures to show how the cups are designed on opposite sides. If you see 2-3 cups in one photo, that is simply showing you the different angles of the cup design.
