Our Best-Selling Acrylic Rainbow Designs are these beautiful Acrylic Rainbow Crystal Tumblers made of molded plastic with great clarity and transparency. This plastic is a good substitute for glass. Merritt takes pride in the quality and design of each acrylic product. Acrylic will not yellow and the colors are weather and sunlight resistant. Although is resists most chemicals found in normal use, dishwasher rinse agents and heat can cause cracking and crazing (hairline cracks) along the sides of the tumblers.
Care instructions: Hand wash all acrylics to maintain optimal appearance. Not recommended for use in the microwave. Do not use a rough sponge or abrasive cleaning brush on acrylic. Straight high-proof alcohol is not recommended for acrylic material as it can cause damage if left in glass over an extended period of time.
