This is a semi-hard case for the erhu. It's very lightweight, you might even forget you're carrying it when it's on your back. It's very convenient for both storage and carrying. It can be used as a backpack, but the shoulder straps are missing, so please prepare them at a 100-yen shop or similar. There are no other accessories. There is some slight deterioration of the inner lining adhesive and some dirt on the exterior due to aging, but it's still in usable condition. It will be wrapped in bubble wrap and packing wrap for shipping. Thank you.
