I got this as a starter kit to go with my first airbrush. It has a lot of the base colors one needs, in my particular case I got separately some Rust, Wood and Cement, not forgetting some Thinner and Flow improver too (which should be from the same brand). The drop design of the bottles is really great for pouring it straight in the airbrush, but I found it a bit thick and prone to quick drying in the airbrush cup so add a few drops of Thinner along.
Pro
well designed bottles, allowing precise drop count
