This coaster set includes four of some of our most popular "sayings". The coasters are 3.5" square and made out of hardboard with a glossy white top. Of course, we recommended keeping them all to yourself, but, the coaster set also makes a perfect little gift for your bestie, new neighbor, drunk uncle... etc. They are 3.5 inches square and about 1/8" thick. They are made of durable hardboard with a glossy white finish on the top. The printing is done with sublimation ink which means they will not fade. Not dishwasher safe - just use a soft cloth (or your sleeve) to wipe them off. They are packaged in a crystal clear hanging bag, ready for retail. Cheers!
