These coasters feature a porous surface that efficiently absorbs liquid, preventing it from dripping onto tabletops and potentially damaging furniture finishes. Measuring 4 1/4" x 4 1/4", with an off-white color, these absorbent, square-shaped stone coasters can be customized with a one color, one side imprint, perfect for displaying a brand name, logo or message.
