Wax melt liners are the game changer of the year!! Made of paper material with a special coating. Simply place in your burner and then add your wax. Allow to melt and fill the room. Once you are done with the melt or just want to change cos you fancy a different scent then simply remove the liner and place in a new liner and add your new wax. When the wax sets you can have fun cracking the hardened wax out. Check my feed for lots of demo vids and liner listing has more info over on my shop. Link
