After my nail got into a terrible accident (with my razor...don't ask), I thought my birthday was the perfect time to pop these things on and take them for a test drive.
The pic above was taken 3 DAYS after I pressed these things on, and I didn't take them off until last night, which was about 6 days later! I probably could have kept them on a few days longer, but a few nails were coming loose at the cuticle, causing hair to get stuck in them when I was doing my hair (annoying!). Removal was almost as easy as application- slide an orange wood stick or similar device under the side of the nail, and gently pull off. My nails were in pretty decent shape after I removed the nail, and today they feel stronger and less brittle. I would say that's the result of the protection from the fake nail covering my real one.
I got loads of compliments, and all my girlfriends could not believe they were press-ons! Give them a try and see if you get similar results!
