Sephora X has some fantastic glitter polishes. Case in point: Firecracker! This is a matte peachy orange hex glitter polish. I’m not sure if this is available anymore, because I found it at Sephora in the clearance polishes, but it might be worth checking eBay and Sephora stores, since they tend to vary.
The formula is great. No need to move around the glitter constantly, and you get a lot out with one swipe. I usually use two light coats so I can get better control over the glitter.
I layered it over Illamasqua Nomad (my fave green polish ever).
