Trumpet Case Triple case only. I usually put in Bb, C trumpets, a music stand, A4 sheet music, etc. Sometimes I put in 3 trumpets (not recommended). There are two storage spaces, outside and inside. The outside is nylon material. The inside is a soft material. If you have any questions or need additional photos, please feel free to comment. I think it's still usable, but please refrain from purchasing if you are sensitive to used items.
