Possible, a cosmetic brush is a rod with a tetrahedral working surface which remained only a bottom part with some traces of a hole. The handle is narrowed. It is decorated with shaded triangles on one side and two longitudinal lines and an S-shape image on the other side. On the end of the handle, there are five transverse lines.
The surface of the bone is properly treated and slightly polished. The ornament is probably made with a metal blade.
