Replacement rubber for the old KUN shoulder rest. The shoulder rest body in the first photo is not included. These are 5cm-long pieces of rubber tubing that I cut from an American-made rubber tube I bought when I used to like and use the old KUN shoulder rest. I now use a resin MACH ONE and no longer need these, so I am selling them. White powder may be attached to the rubber tubing from the manufacturing process, so please wipe it off with a cloth before use. The length is about 5cm, so please cut off any excess after attaching.
