You can indeed re use the flat rate boxes. If you don't want to ship flat rate, covering the box with paper works. I was trying to ship something via USPS in a re used brake pad box and they wouldn't accept it without the box being wrapped, even though I explained there were no brake pads in the box. Evedently they have something against brake pads.
