After looking everywhere for green devil candles, I found this mold, and asked Athena Nelson, owner of Divine Key Tarot, to make them! I am happy with the result. (We're working to see what causes the white cast, but they work fabulously, and I think it ads to their sinister character.)
Use our Devil Heads for numerous spells. Use the red for "Run Devil Run" spells, the green from "Pay Me Now" spells, and the purple for domination!
