I actually painted my nails last week! It's probably the first time this year.
When we were at Five Below I could resist this aqua, yellow, and black glitter polish. I've only bought one of their Funky Fingers polishes before, and it was pretty terrible, but at only $3 I figured I'd give it a try. I painted it over a black base and (go figure) it was one of the worst glitters I've ever worked with! Very clumpy, but manageable.
That night the polish on my index finger popped off. I re-painted it, but the next day both index fingers popped off! I didn't want to deal with it anymore, so I just painted those with a matching teal polish. By the next day I'd lost another nail worth of polish and ended up pulling everything off. I would definitely recommend avoiding Funky Fingers polishes, but wouldn't be surprised if another color suckered me again in the future! ;)
