This is a soft case (manufacturer unknown, brown) that came with a domestically produced double bass. It has a lining (red), but no cushioning material such as urethane. There is no deterioration in the synthetic leather parts such as the head, and I believe it is a case with relatively little signs of use. (The strap to tighten the neck is missing.) It is compatible with domestic 4/4 (overseas 3/4) size double basses, but it is quite tight, so instruments that are slightly larger may not fit. Please be aware of this. It does not seem suitable for use as a case for transporting instruments, but how about using it as a case for home storage to avoid dust, etc.? Thank you.
