If you're going to be outside camping or tromping through the woods, this little kit comes in very handy. It's a "complete bite and sting kit", that has a small, reusable vacuum that can be used to suck out a stinger from a bee or wasp, or even extract venom from a snake bite.
The pump can be used with only one hand, and has four different sizes of cups that attach to the vacuum to use on the various types and sizes of bites.
Aside from the pump the kit also includes alcohol pads, bandages, hair removal razor, and an instruction manual (that you probably won't read). Perfect for chucking into the fishing tackle box or camping gear.
