@Zig: As far as I know they are all matte. I have heard through the grape vine that one of their sparkly colors isn't, but I own two different colors now and they are matte. If you don't use a top coat the polish will neither look shiny, nor will it last more than a day without chipping. The colors, however, are amazing.

I have a bright turquoise by them on my nails right now.
