This is a semi-hard case for a fiberglass euphonium made by John Packer of the UK. It's a sturdy case, similar in construction to those made by Marcus Bona. I purchased it this spring, but have decided to go back to a soft case, so I'm selling this one. As shown in the fourth photo, there is a small tear in the interior, but it didn't affect use. The outer pocket is A4 size.
