First we have Glitter Gal Turbulence, a silver holo.
It is pretty sheer, so over my ridge filler base coat I added a super pale grey cream polish, and then I added 2 coats of Turbulence. On a tester nail with just 2 coats of Turbulence, there was a visible nail line. No top coat is used for these photos. Application is easy and the dry time is good.
Crushed Ego is a dark purple holo, and very pretty in low light too. It is very pigmented so you might get away with one coat, but this is 2 and no top coat.
The holo is really good in them all, but not overwhelming.
