To use these coasters, simply place them under your cups, glasses, or mugs to prevent water rings and scratches on your tables. They're great for both hot and cold drinks. When it comes to maintenance, you can use a damp cloth to gently wipe off any stains or spills. Avoid soaking them in water for a long time as the cork base might get damaged.
