Actually, it was me selling the molds! And they are awesome to work with....not a PITA at all. You pour your wax into mold, level it off with a plastic putty knife, cool bout 15 min., turn over & twist. They fall right out, seriously.....I love them. The main client that I used these molds for changed to a custom mold, so I'm selling off most of these. I am keeping 5 of them for myself though :rolleyes2 Those shown in the picture look like the size of a redhot, the ones I have are like a marble, but cut in half. Yes, you can blend & custom different scents.... It has been done for years. We use to have a place in the mall that sold the chips, (Wicks & Sticks) & you made your own blends...They were put out by http://www.scentchipsusa.com/ they have been making the chips for years. Just thought that I would share the info with you. :smiley2:
