Review (5/5): Great product - super simple and would use again.
These are way easier to put on than I had imagined. Super super simple once you get the hang of it. My only complaint is that you have to be very careful how much you handle the decal or the ink rubs off and you have a bald spot of ink. Also, they don't provide enough of one color in case you mess up. I wanted to put two black mickey's on my pinky but I messed up one so then I only had one black left to use.
Otherwise, I love this product and will re-order again. Got them in perfect time to put on before our Disney trip. One thing I will note that I was worried about is - these decals are not pre-cut so you have to cut them out yourself. I was worried that you had to be super detailed and get as close as possible - you do not. You can cut close enough and the rest is clear so you don't have to be super precise when cutting. Beware of the size of the decal though - some didn't fit on my nail because they were too big.
