Lexmark 50F1000 / 501 Original Black Toner Cartridge for MS310dn MS610dte

This company delivers fast. Carries the extra large size of my HP printer cartridge and HP doesn't may it anymore. Also, the price is 50% less than the small cartridge from HP. I've ordered these carts from Toner Pirate before so I know they last a long time and I've had no problems.
