Scented Crystals Just like wax melts pop a couple of scoops into your clean dry wax burner, they will release a beautiful burst of fragrance into you home. These will usually last around 4 hours before needing to change out if using a tealight burner and longer if using electric burner ( i suggest using an electric burner if you have one) I like to use these when I have guest’s over for a quick burst of aroma. Colour will depend on which scent is chosen. Please note, THESE WILL NOT MELT , they stay in there crystal form. Once you can’t smell them anymore, let them cool and tip them in the bin. Made with only the highest quality ingredient.
