These Halloween spider tattoos are awesome accessories to add an extra scare factor to your costume.
The eight-legged tattoos are found on Etsy shop Buttonhead and they look extremely realistic. This pack comes with five spiders so you can either put them all in one location on your body to make it seem like you have a cluster of spiders on you, or spread them all around to look as if you're getting attacked everywhere! Likewise, you can also decide whether you want to wear them all at once or save some for prank purposes.
If you have a friend who's scared of spiders, you can tattoo spiders on them when they're sleeping so they wake up with a huge Halloween fright.
