Hi all, I’m hoping that someone can give me some guidance. I’m very interested in this game, but no H seam has got me suspect. Can anyone provide more information? Is it just as simple as no H-Seam and it’s a reseal? I’d be purchasing with the intend to grade (I know it’s a little banged up). https://www.ebay.com/itm/WWF-King-of-the-Ring-Nintendo-Game-Boy-GB-Complete-in-Box-NEW-Original-GAMEBOY/224386105311?epid=1245&hash=item343e743fdf:g:3v0AAOSwXplgKUpD
