I found the concept really cool, but they are not THAT easy to use.
I found them quite hard to find the perfect size for each nail (maybe I just have odd shaped nails? haha). Also when applying them to my nails some of them would rip when taking off the backing etc. They are also extremely fiddly, and have a strong nail polish smell (obviously not as much as an actual polish, but still quite bad). The lasting power isn't that great either, they started to peel off after just one day.
There's an awesome range of colours/patterns though, and that's a plus. They're all really unique and cool looking :)
If you don't mind having a short-lived manicure and fiddling around for abit to get them on, then they might be for you, but I don't think I'll be repurchasing.
I personally love doing my nails and having cool new designs on them so i was really excited about this product! Unfortunately i was very disappointed, the strips weren't easy to use and very fiddly when applying them. The nail strip didnt fit my nail so it was a mission trying to shape it to fit. In the end i just painted them with normal nail polish, A LOT easier!
