The Protective Project Mat from Artesprix is made of 100% Silicone which means it was specifically designed for sublimation projects. The perfect partner to your handheld Craft Press, Dry Iron, or Home Iron, it will protect your work surface or tabletop from heat during the transfer process. Because our Protective Mat is made of 100% Silicone, it will capture any dye during the transfer of your design if any gaseous color tries to escape. The black color of the mat will hide any ink and burn marks, so it can be used over and over again. Other Features: Won't slip when you use your handheld heat source, very important! Great to use as a “cool down” area for drinkware and ceramic/metal blanks Protective Project Mat Large Mat Dimensions: 12in x 12in Material: 100% Virgin Silicone Color: Black Withstands temperatures up to 400°F
