• COASTERS FOR DRINKS ABSORBENT CERAMIC MARBLE PRINT– We had this sophisticated table coaster set designed specifically to have the beautiful appearance of marble with all of the benefits of absorbent stone. This special UV printing process has a deep print that does not easily scrub off. • WATER ABSORBING COASTERS 4 inch / 10.3cm round extremely thirsty coaster for the largest of drinks, cocktails, whiskey, beer, soda, water in the home or office. The extra surface area also absorbs substantially more water than the 3-3/4 inch coaster.
