polar lights plastic model box protectors

Hello again fellow builders. I know this may be a long shot but does any body have any of those model box protectors from polar lights that they may want to part with? Or does anyone know of any site that still has them for sale? Been looking for awhile now but google search only brings up two sites that say out of stock.

These were sold in packs of 36 and were meant to protect 1/24 1/25 scale model boxes, kind of like the ones you see for hotwheels.
