i am not seeing it [SEP] these are essentially giant temporary tattoos very similar to the ones you sometimes get as novelty gifts and promotional materiallike those you simply peel off the protective cover press the design where you want it then wet the back of the paper holding the tattoo until it transfers to your skinrubbing alcohol helps wipe the tattoo off if wear and tear and sweat do not take it out firstthe reasons i personally did not care for these a lot less vivid on my skin than in photos or against the paper there is no precut opening for your mouth fyi you get the best result cutting carefully an opening after you put the tattoo on not before very difficult to line up with your own mouth if you wear these over your mouth the activity of talking drinking eating etc rapidly degrades the tattoo causing wrinkles gaps tears etcin my opinion the best use of these temporary tattoos would be to create the illusion of a fake mouth somewhere else on you body like your tummy neck back hand etchonestly i was just really disappointed with these all around
