This is a Marcus Bonna bassoon case. The list price is over 100,000 yen. I purchased it around 2011 and used it for about 10 years. It has been stored at home empty for 5 years, so there is a faint square sun-fading mark on the surface of the case (see the last photo). I think it can still be used, but there is a feeling of use, so please consider it only if you understand that it is a used item.
