Authentic NES Cartridge for the Nintendo Entertainment System.
Pristine: A pristine looking cartridge with few to no noticeable defects.
Good: An average looking cartridge with some blemishes, stains or wear. This could include: Staining (minor), Writing (minor), Label Peel (minor) or Stickers (from previous rental or retail stores). This is what most cartridges will look like.
Acceptable: A cartridge with multiple blemishes and marks that may have bad eye-appeal but will still play just fine. This could include: Staining (major), Writing (major), Label Peel (major or entire label missing) or Stickers (major).
Most games will need to have the contacts cleaned at the bottom of the cartridge. As a cartridge sits it will collect small dust particles on the golden contacts at the bottom of the cartridge which will need to be cleaned. Typically a cotton swab and isopropyl alcohol will clean the contacts well enough for the cartridge to play normally.
