I love this group of colours for light skin tones and crustaceans
You're probably thinking I'm a nut case, but honestly, Ballet Slipper and Pink Lemonade are great for highlights and accents around cheekbones and eyes and Carnival Pink and Havana Red are great for decorating Lobster, Shrimp and Crabs, and some coral.
Other than that, I love the fact that these stack so well, but not so much that the only way to open them is to break the seal with a knife or a fingernail (if you're lucky enough to have them). I'd love a redesign with the second iteration of these where the case was 'waisted' at the join, allowing the fingers to angle in from the outside to the join giving some purchase to break the seal and open the ink pad easily.
Theese inks are perfect to decorate over, paint with, and stamp even a fine design with, with crisp results. Hybrid Inks are the best of both worlds.
