Soft Case for Single Trumpet

This is a soft case for a trumpet. I found it very useful for carrying just one trumpet when my usual double case felt too heavy, but I'm selling it because I no longer need a single case after buying a replacement.

It has a very large capacity, and I believe you can fit plenty of items besides the instrument itself. When I used it, I comfortably stored my mouthpiece, oil, tuner, cleaning cloths, and writing utensils with plenty of room to spare.
While I don't particularly recommend it, the case is large enough to store the instrument even with the mouthpiece attached.
