This is a S. Hayashi alto saxophone soft case, which is becoming quite rare. Although it's a soft case, a plastic plate is inserted on the inside (the part that doesn't touch the instrument) from the top to the bottom on the opposite side of the zipper of the instrument storage section, so it doesn't feel flimsy when touched. And above all, it's compact and light. The metal fittings such as zippers are also sturdy, and I think it's relatively clean, but it's a used item and there is some wear and tear, so please refrain from purchasing if you are sensitive to such things. Returns are not accepted, so please make sure to check carefully.
