KUN 4/4 Violin Shoulder Rest This shoulder rest was used a few times about 10 years ago and has been stored at home since then. The screws have been confirmed to work. There are stains on the box, and some dirt that can be seen in the second and fourth photos, but the overall condition is relatively good. The shoulder rest will be disassembled for packaging because it will not fit in the original box with the screws attached.
