If you are a card player, you will enjoy this set. Made from paper napkins they have a feel of fabric or line. Each coaster has been sealed with 3 coats of Vera-thane polyurethane and has a cork bottom to protect furniture. I would not submerge them in dishwater or put in the dishwasher. They are easily cleaned with a damp cloth.
I also have a set of playing card clips. I offer a "gift" package on ONE coaster and ONE coordinating set of three clips with magnets. You can select this option at checkout.
