Fire Fox was instantly given away. It's is a quite regular red nail polish and it's not matte by any means, because it contains small glitter particles. It just looks weird to me..that's all:(
I really like Powder Puff though. It has a powdery white base with blue shimmer. Yes...blue shimmer...it's not matte at all to me as well. But I like it anyways - coverage is good, only 2 coats are needed for 100% opacity and it's great as a base for nail art.
From the last picture it is obvious that the polish is not matte. I haven't used any top coat at all.
