Viva La Musica Professional Black 4/4 Shoulder Rest I am selling this as I used it for about a month after purchasing it, but it didn't quite fit. I used it for a month and the sound was good, but it didn't fit my body, so I am selling it. There is some wear on the rubber parts, but there are no problems with its use. Size adjustable. Angle cannot be changed. I purchased it for 7000-8000 yen. I will ship it with the box.
