I am selling the case I was previously using because I purchased a new one. As you can see in the photos, one of the zipper pulls has come off, so I've attached a ring as a replacement. Also, there is some wear and tear on the backpack strap, but this part can be purchased separately, so please consider it if you are concerned. It can only hold one trumpet, but there is plenty of space for accessories such as mutes, music stands, and mouthpiece pouches. An A4 file fits in the outer pocket. Thank you for your understanding and consideration. The following is a description from the web: Retail Price: 24,530 yen A Protec case is popular for its stylish design and sturdy construction. This is the Protec PB-301 Trumpet Single & Mute Semi-Hard Case. It has a large storage space, and can accommodate a Wittner 961D folding music stand and mutes (cup, wah-wah, etc.). The outer pocket is sized to fit A4 size sheet music. A shoulder strap is included, but you can also attach a separately sold backpack strap to make it a backpack style.
