Glitter Gal Australia sent me two of their polishes, Nude, and Teal Blue, to try out, and I have to say, I was really impressed. The polishes both had so much depth to them, and the holographic particles picked up light like diamonds. I applied three coats of each of the polishes to reach full opacity, and the polish's formula is a little thinner than I'm used to, which required a little extra caution when applying. That said, these are sparklier than almost any polish I've ever tried out, but they had a smooth finish, not chunky, like most glitter polishes. All of Glitter Gal's polishes are Big-5 free (so, non-toxic) and they are also vegan-friendly. The morning after I applied the polish, I had to do a bit of cleaning around the house, and the polish really held up- not a chip in sight. Although Glitter Gal is an Australian company, they ship internationally, and you can buy the polishes here.
(Disclosure: Glitter Gal did provide these polishes to me as a sample to review, but all opinions are my own.)
