・This is a soft case for tuba, convenient for carrying. This product is free size and mainly compatible with C and B♭ tubas. (1,300 x 850 x 480mm) ・Exterior: 420-denier high-density water-repellent fabric. Insulation in the intermediate layer. Waterproofing on the front pocket. ・Non-slip protective material on the bottom when standing (bell up). ・Shoulder straps for backpack use are fixed with strong rivet processing. Used for about a year in a child's club activities (a few trips), but there is no damage and it is still usable. It was very helpful during transportation as it can be carried on the back or shoulder. I am selling it because my child is retiring from club activities. Please check the condition in the photos as it is a used item, and purchase after agreeing. Thank you for viewing.
