I mainly see this with PAL games, but there will be a sticker on the box for the game. Some tend to have in the bottom right one that says something about Sega Product. I have also seen Knuckles on some telling people to not smoke. Theres been a few Recycle stickers. The question is who put them on there? Most of my PAL games have the Sega Product sticker while some don't. Was this a store thing? Manufacturer? Just curious.
