The Firefly 2 Concentrate pads are Original Equipment Manufacturer (OEM) parts, manufactured by Firefly and intended for use with the Firefly 2 Vaporizers. Each order of this product comes with 3 pieces of stainless steel liquid pads. You can use them to vaporize your solid, liquid, and waxy concentrates. Using these concentrate pads is easy. All you have to do is to press around the edges of the mesh pad until it is properly seated at the bottom of the bowl of your Firefly 2. After that is complete, place a medium amount of material on the center of the pad. Hold the heat button, take slow draws, and wait for visible vapor.
