It is very weird that I haven't posted about OMG yet ... I have no idea why. I've worn it several times, but never deigned to take a picture of it. Whatever. OMG is from the China Glaze OMG collection of 2008, an entire collection of holos. It is a very fantastic collection. The holo is very fine, you can't really see the particles at all. OMG is, as you can see, silver holo. There's a huge amount of holo packed in there ... it's almost blinding in the sun. Awesome.
My only complaint with the OMG collection is that the formula is weird. You have to wait for each coat to dry completely before adding another coat, and then you have to work quickly and without mistakes, or else the polish comes off instead of going on. Ooops. ;)
