These are replacement Volcano Liquid Pads for the Volcano Vaporizer. These volcano concentrate pads are inserted into the Storz & Bickel dosing capsules and loaded into the Volcano Vaporizer herb chamber. Just dab or drop your wax concentrates onto the Volcano liquid pad and load it into the dosing capsule. These durable stainless steel concentrate pads provide generous surface area for efficient vaporization of your favorite waxy oils. Add up to 5 drops of wax concentrate to the Volcano Vaporizer concentrate pads, but we recommend starting with a minimal amount of wax concentrate and working your way up to find the right potency and flavor for you.
