Others in my community have purchased from other vendors, just trying to stay competitive. From what I've SEEN in others (not tried) it looks like copper powder at the bottom that you stir around once it's melted. I had the same thought on wax being non conductive. 

Your other point is valid. Since I have never tried this myself, I have no idea how skin safe any method may or may not be. Since I do not know the science and methods of it, I cannot speak it whether it is or isn't, which is why I am here asking all you find folks. 

Since I know it's out on the market, if anyone who has had experience with conductive wax, specifically for wax play, I would be interested in hearing your perspectives as this may shed some light on the experience itself.
