Blue EVEREST shoulder rest, Spring Collection. - Model: ES-4 - Color: Blue - Brand: EVEREST - Type: Shoulder Rest - Collection: Spring Collection - Size: 1/2 - 3/4 Thank you for viewing. Purchased at a musical instrument store in June. The teacher adjusted it in the lesson, but it didn't fit the height of the child's neck. Regrettably, I am selling it. It was said that it might fit the shoulders and collarbone very well and be comfortable to use, but the child's neck is short, or the height didn't match. It was expensive, so it's a shame, but I would be happy if I could pass it on to a child who is working hard.
