China Glaze Visible Shivers (index and pinky fingers) is a gunmetal-purple shimmer. It's prettier than I thought it would be! This polish was made before the current Big 3-Free era so I'm not sure if you can still purchase it. I'm not sure if it's part of the core collection either. My dad found it at a beauty supply (?) place a few years ago so dusty hunting would be your best bet. I used 3 coats. The formula was thin and a little watery, but still easy to apply. It smelled terrible though, thanks to the Big 3 chemicals in it. It dried shiny so I didn't use top coat.
Native War Paints Black Cat Crossing (middle and ring fingers) has copper, lilac, purple, and silver diamond, hex, square, and star holo and metallic glitters, along with black holo cat glitter, in a glow-in-the-dark lavender jelly base. It was an extremely limited edition polish so I was very lucky to score the last one! My bottle is numbered 5/5. :D I used 3 coats. The formula was good and packed with glitter, but I needed to dab the large glitters onto my nails. I didn't have trouble retrieving them though. It dried bumpy so I used top coat to smooth it out.
Thanks for looking! See you on the other side of the day!
