Scent Puddle Wax Melting Tart. Each one is 2 oz of rich fragrance to fill your home with luscious fragrance! These can be easily popped out to use in a warmer to try a new fragrance. Terrific way to find out if that new fragrance is right for you! If using in the Plug-In Tart Warmer, cut in half with a butter knife to prevent overflowing the dish.
