The one can never be too percautious and especially on the road. This sort of vampire killing kits were purchased when people would travel to eastern Europe and especially to Transylvania, the home of Dracula! The kit contains all sort of anti-vampire stuff, from cross, through all sorts of daggers and guns with silver bullets, till garlic and hawthorn pointed peg. I guess the adventurous travelers were quite disappointed when they reached the castle of Dracula and it turned out to be just some dull Middle ages palace of even duller duke that got this nick because he was very severe ruler. They didn't get the chance to use their cool, new and awesome vampire kit. Now, you can see this sort of traveling equipment only in museums as a reminder of our ancestors' crazy believes!
