Quite a good base for shaving brushes. Allows the placement of brushes for drying with a knot diameter of up to 26 mm (after shaving, for those who do not know, the brush needs to be placed upside down until it dries, so that no moisture passes into the base of the knot and affects the adhesive substance that holds it in the handle of the brush).
Of course, because it is metallic, one could press the ends outward to increase this distance by 1-2 mm.
