Thank you for viewing. This is a KUN brand yellow fractional violin shoulder rest. It can be used for 1/16 to 1/4 size violins, allowing for extended use. It folds up, making it compact for storage. My child used this with a 1/4 size violin, using gauze padding. It is in good condition, but please understand that it is a used item. I will carefully package and ship it. Thank you. - Brand: KUN - Color: Yellow - Type: Fractional violin 1/16-1/4 shoulder rest
