SG: CLEANING SYSTEM-SEGA- (USED)

What condition is this item? After the title are the follow explanations of description:
(GAME) = Game cartridge or disc only.
(BOX) = Original box and cartridge/disc.
(COMPLETE) = Original box, book, cartridge/disc included.
(NEW) = Brand new, factory sealed.
(NM) = No Manual Included when NEW (new games have manuals on disc)
So if the title is "SUPER MARIO BROS. 3 (GAME)" then you know the game is cartridge only!
Note: If there is something major wrong with the game, we also list it here. For example: (BAD LABEL) = Something wrong with the label, possibly removed. Inquire for more information.

The Cleaning System is a simple device which simply extracts dirt. Unlike other cleaners, it requires no fluids, although depending on the situation this may mean it does not fix the problem. The bottom, thinner side is for cleaning cartridge slots, while the top is for cleaning Mega Drive cartridges. The cleaning operation simply involves inserting and removing the device.
