The  square cork coasters are lightweight with a natural coloring that makes them a neutral decorative element for your home. Cork is naturally absorbent, so they’re a great option to protect against drink rings caused by condensation build-up on glasses, cups, mugs, or beverage bottles like wine or beer. Plus, the cork material is gentle on table surfaces. The square coasters come in packs of 25 and are available at a cheap price, so you can give them away in full sets of 2 or more.
