The square glass coasters made of slate add a decorative, rustic flair to your table setting while protecting its surface at the same time. Placed under a cocktail, teacup, beer or wine glass, the coasters prevent unsightly water marks or other drink stains. Scratches are prevented by the protectors on the underside of the wine coasters. The small slate plates also look great under raclette pans or as candle coasters. Please note: Slate is a natural product. This layered stone cannot be cut 100% straight. Chipped edges may vary. There may therefore also be slight variations in thickness, length and width. Wipe with a damp cloth before first use.
