It's awesome, I really really like it. I want more matte glitter haha. Also over Max Factor - Cool Jade I get cherry blossom vibes which I love. Unfortunately I used my bad topcoat and I didn't wait long enough and I got bubbles :/ Thankfully they're not too obvious.
The coverage was great, it was really glitter dense (which I'm always a supporter of). CMX321 consists of medium pink, spring green and white hexes with smaller red and blue hexes and small white hexes and squares. Super interesting.
I used 2 coats and then some placing, not difficult to work with. The green hexes were the most sparse in the mix so it was fun getting some on each nail (yes I find these things fun). Oh another thing CMX321 is such a lame name, I would've been happy with anything other than some letters and numbers.
I like glitter. A lot. Probably too much. I enjoy it. Haha thank you for reading and I hope you have a great day!! :)
