Yeah I know they have that stuff.. they used it to patch upmy arm in a hockey game when I needed stiches.
BUT I'm too cheap to buy that stuff, plus I think its useless. I grew up with never using band aids when cut. My dad grew up on a farm in Greece, they never ever used that kinda stuff, it was seen as unnecesary. I dont even have regular bandaids! lol
The only time you should use bandaids is when you initially get cut, so it helps stop the bleeding, then you hsould take it off and let the air do its work to heal it.
