I was not expecting these to be so big which is a good thing, I expected a smaller size sheet like you often see with these type of temporary tattoos but they are huge. And the detail is immaculate none of that pixelization or blurry images here, they are clear and well printed with vivid color. So I did the only thing I knew to do to “test” these. I put one on my arm and forgot about it over the weekend. I made no effort what so ever to care for it in anyway, I slept with it, showered with it numerous times, I even mowed my yard (October in Florida is still very warm out think the high was 85 that day) and the temporary tattoo never changed until finally on the third day I started noticing wear. Came off in seconds with some ipa (alcohol). Moral of the story here, if you are getting these for a costume party or a cosplay event or something as far as I can tell unless you go nuts (you wanna get nuts? Cmon let’s get nuts) these are gonna stay on and stay clear for an entire weekend and if you’re partying longer than that with these, first can I come too and second, that’s the only case scenario I can see these NOT lasting. They could be used for really any costume requiring tattoos (biker, nun, whatever) so there’s that also. Long story short, you may be damaged like the joker but your temporary tattoos probably won’t be through your Halloween bash. Maybe this will be that one little push you need to buy these really great costume accessories. Shipping was fast so get them now for the spooky season or your next cosplay event.
