QMX Supernatural Devils Trap Doormat Stop a demon in its tracks with the Supernatural Devil's Trap Indoor Doormat! If you're like Sam and Dean Winchester of Supernatural, you just never know who might be stopping by to visit. Be prepared - get yourself this handy Devil's Trap Doormat! Similar to a circle of salt but more powerful, the mystical symbols on this richly printed nylon-fiber mat will help keep you safe. Sure, Crowley will whinge about it, but it's just the sort of greeting he'd expect from friends of Moose and Squirrel. The doormat is nylon fiber with a thermoplastic rubber backing. This rug has a 24-inch diameter, but its mystical powers know no bounds. Just say yes to rugs! Check out our Supernatural Anti-Possession Symbol Doormat for extra protection against demons!
