This is a full-size Bon Musica shoulder rest. The shape of the metal parts can be bent, allowing you to adjust it to fit your body. It provides excellent stability. As you can see in the photos, there is wear on the sponge parts of the legs and the main body sponge, as well as peeling of the paint on the main body. There are no problems with its use, so how about it for those who don't mind scratches, or those who want to try this type at a low price?
