Review (2/5): I'm not seeing it
These are essentially giant temporary tattoos very similar to the ones you sometimes get as novelty gifts and promotional material.
Like 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 skin.
Rubbing alcohol helps wipe the tattoo off, if wear and tear and sweat don't take it out first.
The 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, etc...
In 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, etc...
Honestly, I was just really disappointed with these all around.
