I already swatched Anti-Freeze a while ago, but I recently bought a few more on ebay so I thought I'd do a comparison. I did these all over Diamond Cosmetics Crushed Velvet which is actually a dark purple, but it looks blue in the pictures.
All of them go on clear and the glitter is iridescent. The glitter in Arctic ranges from cerulean to teal, depending on the angle. The glitter in Krypton-Ice goes from teal to yellow-green. Orange Slush's glitter goes from red-orange to yellow-orange. Pink Ice has the same glitter as Orange Slush, plus a royal blue glitter. Anti-Freeze has the same royal blue glitter as Pink Ice, but also small specks of pale green glitter (possibly the same as the glitter in Krypton-Ice).
I really love all of these! Even though I only wore the different colors on each finger for this comparison, I loved wearing them so much that I did it on my other hand too. There's a good amount of glitter as a top coat, I am wearing two coats of each color. Not dense enough to wear by themselves, though. As much as I love these, I do have some complaints. First of all, they REEK! I'm sure it has to do with the chemicals (pretty sure these are not 3-free) but whatever the reason, they smell like rotting garlic or something. I don't even mind the smell of most nail polishes that much but these smell gross. The other big complaint I have is that they do not seem to mesh well with 3-free polishes. I put Seche Vite over my mani, but it was still dent-able for at least two days, maybe more. Also, I'm not sure if this is a well-known fact that I am just discovering, but it seems like when you put SV over polishes that take a very long time to dry, small cracks eventually form in the polish. Weird. Still, I love these glitters so much that I am willing to deal with it all; I don't think there is anything similar out there right now.
I know people have been able to find these at their local Dollar Tree locations, but I bought these on ebay. If you are lucky enough to find some, pick them up!
