I was pretty IMPRESSED with these stick on nails. They have a sheet of glue on the back of it already which is convenient. They have numbers on the back of it to, so you can match the right size to your left fingers and right fingers. A+! I must say this lasted about 4 days of wear when i think it says up to 7 days on the instructions. Maybe i just worked up too hard with these nails and did hard labor to ruin them so quick. This would be great for prom, homecoming, weddings, quick photoshoots and such. These didn't ruin my nails when taking them off, when gel nails going to the salon do ruin your nails. I recommend these if you don't want to ruin your nails or want to pay less for nails. These weren't hard to get off my nails and pain free. These press nails come in different colors, patterns, and lengths.
