Each box contains two (2) TN 850 black ink printer toner cartridges ready and able to print each page sharply time after time. Each TN 850 black ink cartridge yields up to 8,000 pages pages (5% coverage, Letter/A4). Featuring extra capacity to hold additional ink and toner, print much longer before needing to replace this cartridge. TONERNEEDS TN 850 toner cartridges use an exclusive patented ink formula to make sure your printing produces clear and sharp text lines and look vivid even if the color of the image is limited to black and white. Save time and money and skip the headache of having to frequently reorder printer ink! TONERNEEDS printer cartridges and drums are thoroughly inspected and tested before leaving the factory to ensure they have full working compatibility with your printer. Our cartridges come with original ISO9001 and MSDS certification. ?????? What's Inside the Box? ?????? Package includes: 2 x TN-850 Black Toner Cartridges (NON-OEM) 1.
