4 different sizes, each holding 1-4 brushes and you can choose between the wall mounted option, or the mount-less desktop version.
There's two variants, one more suitable to be used with Electric brushes, and the other with Regular ones. The difference is a smaller hole and a longer neck for the R models, sizes below:
33x39mm Electric
20x26mm Regular
