It’s an individual hanger designed for “outside wear”, such as umbrellas, scarfs, handbags, coats, hats and more.
A single strip of natural rubber is hold together in its extremities, with a snap metal button, creating an elliptical ring.
In the male part of the button a screw is inserted so it can fix the ring to a wall, in a vertical position. The female part covers the screw so that visually there is only a rubber ring.
The natural tension of the rubber allows the object to hold its shape when in use.
