A4000 cardboard box for sale on ebay

[A6000]

If he had a 4000 and sold it, why didn't he send it in its box, if he still has a 4000 he should keep the box for when he does sell it.

The seller of this box is also selling an empty a4000D case, very yellowed, but good enough to rehouse a 1200 maybe.
He has 41 items for sale, but I don't think he has cannibalised this 4000.
PS. Perhaps the person who buys the case can get it sent in its box.
