This little metal coaster charcoal burner is great for burning loose sage, resin. Charcoal tabs are sold separately. How to use... You add sand to the bottom if you like, you grind up the charcoal tab up and spread out along the bottom with or without the sand. It really is your choice many do decide to use the sand for extra protection to the bottom of the dish. Once you line your dish you can burn cones, resin and loose sage.
