More stocking stuffer stuff I found at DODGenie Mini Light Weight Keychain with UV light (Buy 3 Get 2 Free) $1.25 each (shipping was flat rated for $7.00)

Linky

Specs;

This is a must have gadget! Just think of all the useful things you can do with this! Never again wonder what lurks about your motel/hotel bed and linens, this powerful light gives you the ability to detect semen, blood, and urine by the touch of a button. You also have the ability to catch counterfeiters in the act by spotting a fraud by the flash of a light. Who knew finding fake money and undesirable fluids in your bed could be this fun! But the fun doesn't stop there, this little keychain transforms the Average Joe into the kooky Inspector Gadget by providing, not only the UV light to detect all kinds of goodies, but also a super bright LED directly on the other side so that as you lurk about the filthy stuff you can scan the perimeter for perps in the act!
