Serendipity is a yellow linear holographic with a strong red flash. The holographic flame isn't quite as bright as most of the EPs I own, but it's hard to get a strong rainbow when you have a delicate pastel base. Application was easy without pooling and didn't require much cleanup. I used three coats for full opacity. Dry time was average with one coat of KBShimmer's Clearly on Top.
Hatched is a lovely yellow crelly based polish with pink, fuchsia, and lavender hexes as well as blue/green iridescent hexes and shreds. Application was amazingly easy, and there wasn't any pooling or need for cleanup. I wore three coats without undies because I wanted to get that lovely depth you get when you wear glitter crellies. Dry time was average with one coat of KBShimmer's Clearly on Top. I only needed one coat of topcoat because the glitters were very tame on their own.
Both of these are older polishes and are a bit harder to find, but they do pop up on blog sales every once in a while! Just keep your eyes peeled!
