Massage roll

Massage roll by Artist Unknown. The object has a long, cylindrical white handle made of stone or ivory, with a dark metal collar at the top. A dark metal frame is attached to the handle. The frame is roughly oval-shaped and has a textured surface. Five clear glass balls are attached to the top of the frame. The center ball is smaller and cylindrical, while the four surrounding balls are spherical. The background appears to be a light-colored fabric or paper with a subtle texture. A ruler or measuring scale is visible at the bottom left corner.
