This is a violin shoulder rest. Unfortunately, it didn't fit me, so I'm selling it. The part that rests on the shoulder is soft and flexible. It's recommended for those who dislike the stiffness of traditional shoulder rests or the right side of the shoulder rest hitting their left chest. The height of the shoulder rest can be adjusted using the included tool. It's very lightweight. - Model Name: HAYATE 47 - Accessories: Switch tool, instruction manual, business card - Materials: Leather, metal - Colors: Black, brown - Purpose: For violin adjustment I purchased it about three years ago for 22,000 yen. Please understand that this item has been stored at home. I'm sorry, but I'm not considering lowering the price at this time. Thank you for looking.
