retro console official boxes?

does anyone know if there is a retro company out there that sell on old console boxes only. i have some old consoles i would like to keep in very good conditon but they are missing the original box. master system 1, megadrive/genisis 1, snes (pal). luckily i have the boxes the most my consoles as i purchased them new but most i bought 2nd hand over the years were unboxed. i remember one my gamer mates mentioned he purchased a box for one of his retro consoles but it was a while ago and we lost touch and i cant remeber where he said he purchased it (ebay more than likely. even reproductions of soem of these boxes would be a good idea.
