This is a genuine Canon PFI-101MBK matte black Lucia ink tank, 0882B001[AA].  It is designed to fit the Canon imagePROGRAF iPF5000 and iPF6000S.  This ink is part of ink set F.  THIS INK IS EXPIRED, but it has been our experience that these cartridges work just fine well beyond their expiration dates.  This is great OEM ink at a great price!
