Trumpet Case Triple case only. I use it to carry Bb, C trumpets, a music stand, A4 sheet music, etc. Sometimes I put three trumpets in it (not recommended). There are two storage spaces, one outside and one inside. The outside is made of nylon material. The inside is a soft material. --------------------- From the XX Instruments website: Brass Bags trumpet/flugelhorn double case. Weight: 3.3kg (excluding straps) Size: Length x Width x Thickness = 55 x 35 x 20 (measured, excluding handle) Includes backpack straps, space for two instruments, mutes, accessories, and A4-size sheet music. Features: Brass Bags is a British manufacturer of high-quality soft cases. Although not well-known in Japan due to the lack of an import agent, it is a famous manufacturer overseas for its lightweight and durable cases. It securely protects instruments inside the case with thick cushioning. This model is a double case for trumpet and flugelhorn. There is space above the flugelhorn to store multiple mutes, and it has excellent storage capacity. "It's difficult to carry two instruments around every time with a heavy hard case, but I'm worried about a soft case..." This case takes the best of both worlds. --------------------- If you have any questions or need additional photos, please feel free to comment. It's still usable, but please refrain from purchasing if you are sensitive to used items.
