Sadly, or fortunately (?), my nails are too curved. I managed to snap a few pictures, and then the decals on my accent (ring) finger gave in. I'm not sure if the adhesive was strong enough. I didn't get a chance to try to activate it with an NFC item. Luckily, Cathy from More Nail Polish Blog made an amazing post with a video, please click!
The decals were ok, but the strips were better. They are really colorful, and they did stick for about 24 hours until I decided to remove them. They are easy to apply, along the lines of Incoco and Sally Hansen. However, after I wore them for a whole day, I noticed shrinkage. Again, it might be due to the shape of my nails and the fact that I had to stretch them a bit to avoid wrinkles. These are really affordable. Check them out here.
