Our coasters are small, flat pieces of acrylic used to prevent drinks from damaging furniture or other surfaces. Protecting furniture from water rings and damages caused by beverages is a common household and workplace use for coasters. Coasters can be used for a variety of purposes. In addition to preventing water damage to furniture, they can also be used to soak up any accidental drips or spills from beverages. It's not uncommon to use custom coasters as a decorative accent in one's home or place of business. These coasters are durable and you can depend on them to protect whatever surface they are on from water.
