Waterproof custom cards are specifically made to resist damage from moisture, making them perfect for use in wet and outdoor environments. These cards are produced using waterproof cardstock materials which are synthetic polymers or treated paper. Moreover, text, images, and colors are printed on waterproof cards using inks and coatings which are fade and water resistant. Waterproof custom cards are most commonly used for event wristbands, loyalty cards for swimming pools and spas, and outdoor ID cards, giving durability and dependability in harsh conditions
