1 quick question regaurding some current ebay aes carts

i was just wondering if anyone has seen the motw and blazing star aes carts currently on ebay. does anyone know if those are stickers on the lower back portion of the cartridge cases. if they are stickers why are they there? are they common? and can they be removed? thanks for the replies.

Well, I just looked at my B.Star and I can say that there is no sticker on the ebay copy.

I suspect this is the case for Garou as well.

The only game that I have had sticker on cart case is Neo Turfmasters, US version, pretty much all Jp carts have the serial number printed on the inserts.
