Great Product

These coasters sublimate easy and the end result is pretty good. They have a smooth back so I don't worry about them scratching furniture. Be sure to wipe them before use. I used soft cotton cloth. If there is any moisture or dust on the surface the end result will be white spots in your sublimation

These are perfect for the patterns I created for a craft fair.
