Hi 2 cute !
I don't use the hair dryer any longer. When you use it the perfume is melting but you cannot change the discolouration. You can eliminate fingerprints or something like this. When the perfume is melted and the air stream is to strong perfume can get out of the box. You must be very carefully. When the perfume is harden again
it looks a little more shiny than the original filling. If you want to fill an unfilled box with original solid perfume its better to melt in a little pot in water on the stove to make sure that it's not to hot. When it's to hot it began to smoke and you get a discolouration too. First you can try it with beeswax and almond oil how it will work.
There are interesting recipies for solid perfume to make by yourself. Hope this will
