Tinkerton Scientific Supernatural Defense Systems has just released it's first kits. This is the Ghost Hunters Kit, which includes:
Real Graveyard Dirt (Procured by Mr. Tinkerton)
Anti-Possession Ectoplasmic Barrier (applied topically)
Magic Amulet to control evil spirits
I will have these kits, as well as the the others, available for sale at Steamcon IV this year in Seattle.
