The adhesive on the contact surface has deteriorated, so it doesn't stick to the instrument body. Therefore, the condition is listed as poor. Otherwise, it's in used condition, as expected. The box also has some damage and dirt, so I will fold it up and ship it as compactly as possible. I hope those who understand this will consider purchasing. Acousta Grip by Stern Sound Concert Master Thick CMT601 Violin & Viola Shoulder Rest made in the USA Thickness: Approximately 4 cm For Violin & Viola "The developer and owner, world-renowned violinist Albert Stern, uses this shoulder rest on his own Guadagnini violin for concerts and recordings. He says that the resonance of the soundboard is far superior to shoulder rests that are fixed with legs, and that the overtones seem to bloom. When putting the violin in its case, placing this on the instrument's surface (over the bridge) and closing the lid will increase the security of the instrument, and it can be stored inside the case."
