Set of 6 Beautiful Wolf Winter Scene beverage coasters. Anti-skid Neoprene coaster with black backing. Measures 3.93 X 3.93 X .04. The anti-skid rubber backing on our square neoprene coasters makes them an ideal choice for outdoor activities such as pool, patio, and boating. Neoprene is a synthetic rubber that is flexible and stands up to temperature fluctuations so it is sure to withstand your hottest and coldest beverages without breaking down! It provides a non-slip coaster that won't move around or be compromised by condensation or spillages. The printed top is polyester fabric so condensation absorbs into the fabric and your drink will not slip around on the coaster like traditional hard top coasters (don't you hate that?) These coasters are the last coasters you'll need! Please note these are printed professionally on demand They make a great gift or addition to your home or office décor.
