We've featured a couple other vampire killing kits (not to mention zombie killing ones) here on Geekologie, but I particularly like this one because it's nice and discreet. Typically, it just looks like an old art print (lower right in photo), but slide the front off and TA-DOW -- a mirror, cross, garlic, holy water and stake.
So the next time your suspicious friend who only comes over after dark and stares at your neck is in your room, whip out the mirror from this, and if there is no reflection, you'll be glad the rest of what you need is at your fingertips! Yeah!
I've got news for you: if you whip out that mirror and your lady friend doesn't have a reflection, guess what -- you just had sex with a vampire! High-fives all around! Now stake her.
Thanks to Mike, who's never killed a vampire but has slayed two dragons.
