The document defines the grading terms A, B, and C that are used to classify toner and inkjet cartridges based on their condition. An A graded cartridge is brand new and unused in the original retail box manufactured after 2010, while a B graded cartridge can have minor defects or be in a previous box style. A C graded cartridge is unused but in an opened original box. The prices quoted are for delivery only and subject to the seller providing accurate information about the cartridge condition and grades.
