They are a simple pain free way to enjoy sporting tattoos and tattoo culture without going all the way to get permanent side effects. They can come out easily as well with use of soap and water or oil based creams, and they are basically intended to last just a few days. They are usually applied to your skin using water to transfer the design in temporary form to the surface of your skin. These are not real tattoos but rather they are stickers, just like a decal. For anyone who is not sure they will want a permanent tattoo may want to begin here.
