You can pour 6 hearts of wax that you perfume as you wish into this plastic mould for making scented wax melts. Finished products are designed for use in an aroma lamp where they slowly melt above a tealight candle and release a scent into the surroundings. You can easily pour melted and scented wax into the heart-shaped moulds and wait until they harden. We recommend using a special wax that’s developed to carry and hold fragrance well. After closing, the mould creates a practical box that you can use as a beautiful gift packaging or a packaging for sale. With careful handling, the mould can be used repeatedly.
