This marble coaster is the perfect addition to any coffee table, living room, dining room, kitchen, bar, or office! You could even put it in your bathroom if you want! The coaster is approximately 4"x 4", or 10cm x 10cm, or full dilation for a pregnant woman, with our original images transferred to each stone. Don't use as a trivet...don't do that. The coaster is also waterproof for condensation from your cold glasses, but not dishwasher or deep sea diving safe. The coaster can be cleaned by wiping with a damp cloth. Finally, each coaster is backed with cork in order to protect your beautiful furniture. Each tile is unique in it's own markings, giving every coaster it's own original look and vintage feel.
