This is a Protec single case, navy blue. The product number is BM307BX. The shoulder strap is unused. The exterior is a hard case, making it a convenient case that combines compactness and sturdiness. I purchased it almost two years ago and used it to store a sub-instrument. I usually kept it in a dark place, and I only took it outside once or twice. I think it's in a clean condition with no noticeable damage to the hardware or the main body, but there are some minor dust and scratches.
