I ordered the mixed packet containing 4 black, 2 red, 2 blue and 2 green pins. The pins glide nicely on the whiteboard and a decent size for writing. Unfortunately, the two pins of the color green are useless. It makes it seem as if the paint diluted with water, the color is very weak and barely visible from a greater distance. After about half an hour, the green color has dried up and is still more difficult to read.
