I have used the Sally Hansen nail polish stick ons several times so I was excited when I received this sample in my box. I cleaned and buffed my nails before application as instruced on the packaging and began application. Application was just as simple as the Sally Hansen stips except Sally Hansen gives you a small file and another tool to trim them to fit your nail. For application I used a small pair of nail scissors I already owned to trim the stickers down and it worked perfectly. As another review stated I would not recommend using a nail file on the Incoco brand stickers just because when I tried it the file roughed up the edges enough tobthe point it made the stickers peel/chip off in 2 day, drastically effecting my wear time. I'm also rough on my nails too - overall I think the Sally Hansen ones last longer. However I did like how the Incoco ones dried, with Sally Hansen stick ons you feel like you have stickers on your nails with Incoco they dry quickly and feel more like you've painted your nails yourself.
