We will be removing each card from its slot, putting it inside an antistatic bag, bubble wrapping it, laying it horizontally inside the box and taped down if required (likely for singles and doubles). Then the box itself will be bubble wrapped, and surrounded by instapak foam, inside a triple carrugated cardboard box, with an extra lid on the top and the bottom. Then more duct tape. One can never have too much duct tape

PS. Time permitting, I will try to make an unwrapping instruction video, so you will know how to get mining within 15 mins or so. Failing that, I will provide text instructions and answer questions here.
