This is a handmade trumpet mouthpiece pouch crafted from high-quality, domestically-produced Tochigi leather, vegetable-tanned nubuck. This pouch uses stiff leather, so it will take time to break in, but you should be able to use it nicely while maintaining its firmness. (Due to its stiffness, it's recommended for use with standard mouthpieces.) The approximately 2mm thick, sturdy leather protects the mouthpiece. To prevent it from opening during travel, etc., a Japanese-made jumper hook is used as a fastener. Color: Chocolate Stitching: White The metal parts inside are a double-layered structure with leather patches. Sewn finish for longer use. Since it's vegetable-tanned leather, you can enjoy the aging process as the appearance changes with use. *Please note that due to the natural materials and handmade nature, there may be scratches or minor imperfections. Please refrain from purchasing if you are overly concerned about these details.
