Mike...it's a lead I got from someone local who I know. Not sure where they found the guy, but they aren't able to swing the money for the purchase.
Steve, thanks for the info about the flaps. I also know the roller mark should go one direction (long to long). I'm not really sure what I'd plan to do with them, to be honest - might be a flip, might open the 20 and sell the box, might open it all - really no idea.
Here are some pictures from the seller...first 5 are the lot of 20 packs and 1000 singles and two boxes, #6 and 7 are of the complete box...
