Now you might be thinking, "Okay, so basically this tool gives me great insect venom removal effects, right?" Absolutely, but guess what? It can even do much more. That's right, you can use this emergency extractor to remove not only insect venom, but also snake venom in case you get bitten. This makes it all the more useful, as many snake venoms have serious health consequences and early intervention often increases the success of treatment. This set also includes a handy pressure bandage in case you need to use it. The suction piston has two sizes of suction heads, so you can choose which one to use depending on your bite.
