Replacement rubber for old KUN shoulder rest, 4 pieces

Replacement rubber for the old KUN shoulder rest. The shoulder rest body shown in the first photo is not included.
This is a 5cm length of American rubber tubing that I cut to size. I purchased it when I was using and liked the old KUN shoulder rest. I am now using a plastic MACH ONE and no longer need it, so I am selling it.
White powder from the manufacturing process may be attached to the rubber tubing, so please wipe it off with a cloth before use.
Please cut off any excess length after attaching.
