I love these clamshells. I'm using a mix of IGI 4625 & 4627 for my wax melts and can fill 7 from 1lb of wax. Getting them out of the clamshells does take a little bit of work though, but it doesn't seem to be out of the norm (it seems that some commercial brands of melts are soft and very difficult to get out of of their packaging). I did a test and put one in the freezer to see if that helped with the release. It did, so that's something I'll make sure to share with my customers.
Well, back to melt production. :)
