The same, super slick material used by bakers. Dab mats are a must if you use concentrates. Non-stick silicone mats keep sticky oils off your tables or counter tops. They're made from woven fiberglass and silicone, and heat resistant up to 450 degrees Fahrenheit. This one is 4 1/2" x 4 1/2", and is available in black, blue, yellow, green, red. Dishwasher safe and easy to clean.
