Please note: This is for a 1/2 size, not 3/4! This is a 1/2 size contrabass case from GEWA, a German company. I bought it as a flight case to further protect my cello when loading it onto a plane, but it didn't fit, so I'm selling it. If it were the right size, I wouldn't want to part with it, as I found it to be very functional. By the way, it cost 38,500 yen. Specifically, it has a pocket for bows, a pocket for small items, and a pocket for sheet music. It also has a handle on the top, back straps for carrying it on your back, and hooks for attaching accessories, allowing for easy customization. The inside was also fluffy. It has many handles, making it easy to carry in various ways. I felt that it would securely protect the contrabass. GEWA is a long-established German case maker that also makes cases for violins, cellos, and other instruments. They are a manufacturer with excellent technical skills.
