This is a height adjustable Wolf Forte-Primo shoulder rest for 3/4 to 4/4 size violins. This shoulder rest is made in the Netherlands and is known for its quality. The shoulder rest is used but still in reasonable condition - the rubber feet are a little bit worn and one black rubber band is missing. There are few chips off the edges of the foam (please see pictures).

If you have any questions, please do not hestate to contact me. Thanks for looking.
