I'm selling a KUN collapsible shoulder rest, like NEW, that fits 15-17" violas for $40, OBO.Its unique design allows feet to collapse down onto rest for easy storage. Kun's patented locking device limits unnecessary rotation. This design is nearly identical to the Kun Original except for the underside material being brown in colour instead of black. Very handy for those with shaped cases or those with insufficient space to store the standard Kun shoulder rests.Feel free to ask if you have any questions.
