Cover it up in cardboard and ship it. If you work in an office just ask if you can take a cardboard box or two and proceed to cut out squares that are slightly larger than what you want to try and wrap the guncase. With the extra cardboard around the sides just score it to the right size (this is to "reinforce the corners") and tape together your multiple pieces of cardboard along those parts that you've scored. Put a shipping label on it and ship it out.
