Army Painter Speed Paint is a fantastic paint range that can save bundles of time in miniature painting. Their labels, though, do a poor job of truly showing what the paint will look like on the model. These toppers can be painted and glued onto the paint bottle caps to act as a swatch to provide a true sample of what to expect of each color.
