Fuliko 40 Pack 4 Inch Round Diatomite Coasters — Water-Absorbing Stone Mats for Soap, Cups & Bottles

These Fuliko diatomaceous coasters are made from porous diatomite that soaks up water quickly — tiny surface pores draw moisture away to leave countertops neat and dry, ideal for bathroom and kitchen use. Use them as water-absorbing stone mats under soap bars, cups, soap bottles, dish sponges, water bottles and other items to prevent puddles and water marks. Cleaning is simple: rinse with clean water or wipe with a damp cloth and let air-dry; for stubborn stains, gently sand the surface with sandpaper. Pack contains 40 pieces; each round coaster is 4 Inch in diameter and 0.35 inches thick.
