They're super easy to apply and require no drying time, but the process is a bit longer than simply painting your nails. However, you do end up with salon quality results.
The only thing I really disliked was that it chipped uncontrollably the next day. The "polish" hardened nicely, but the littlest nicks to your nails would result in a chip. I didn't apply topcoat (because I assumed I didn't need to) and I think that could have prevented the problem.
Another disadvantage is the price-- almost $9 per box. I'm not too sure if I'd repurchase again, (considering it wasn't a lasting manicure) but I do love the wide range of colors and designs available, as well as how neat the stripes applied!
Have you tried these and had the same problem?
