Our little muffin tarts are .80 ounces each. Soy Tarts are to be used with a tart burner. Our soy tarts are made without paper cups to limit the amount of waste in the environment. Our highly scented soy tarts are loaded with twice the amount of fragrance as our highly scented candles. Wrapped in our natural plant cellophane and organic/fair trade hemp ties. The fragrance in these soy tarts lasts about five times longer than our tealights. You’ll need about 5 tealights for each highly scented soy tart, or use an electric burner. Because of the small size, you can mix and match different scents to achieve your desired fragrance. If you don't want your soy tarts highly scented you have the option to customize them light or medium.
