Indoor no flash.I used two coats of OPI Can’t Find My Czechbook as undies and two coats of Peacock Portrait. Over all I really like this polish. Even though it’s a beast to photograph. It’s literally too sparkly to photograph properly. I still really love the finished product though (even if it doesn’t play well with my camera). My only complaint is that like a lot of Finger Paints nail polish it takes quite a while to dry (longer than other brands (OPI, China Glaze, Etc.). But if you like blue sparkles then you will want to pick up a bottle of this from your local Sally Beauty Supply ASAP. Well that’s all I have for you for today. Until next time, stay classy, and stay polished.
