Thank you for viewing. Case size: Bell 48, Height 118 (Storage size: Bell diameter 440mm, Height 950mm can be stored) This is a soft case for small to medium-sized tubas.

I used it with a BbTUBA YAMAHA YBB-105. The overall construction is solid, so it is a bit heavy, but the inner cushion is also firm, so the safety aspect was very good. Also, the pocket for storing sheet music etc. is large and easy to use. I replaced it immediately (I bought it because I had to transport it urgently and couldn't wait for the custom-made one), so I only used it once and it is very clean.
