Used only once, I have five identical rectangular electric guitar shipping boxes. They were used to receive empty cases, and before I cut them up for recycling, I figured someone might need them. They are stapled and taped, and in shipped-one-time condition. Take one or take 'em all; first come, first served. Message me, and I'll send you the address. If you need more, I have a few other E guitar and E bass boxes in various conditions, but still usable for shipping or storage.
