Loved every piece of it. I did end up cut some it to fit my design better. They stick on pretty well all night through my sweat.

Nice for raves/festivals
A good set of pre-arranged face jewels. Quick and easy to apply compared to sets that just come with individual pieces meant to be placed one by one. Goes on easy, adheres well. A nice way to spice up a night out.

fun face gems - takes the guesswork on figuring out design of face gems
Simple to put on a nice face gem design. Just peel and stick. You can make it last longer by just doing one side per use instead of applying one whole sheet at once. Doesn't hurt when removing and no irritation afterwards.
