Verified Purchase(What is this?)
This review is from: Set of 4 Compatible Lexmark C540 Laser Toner Cartridges. Black - C540H1KG, Cyan - C540H1CG, Magenta - C540H1MG, and Yellow - C540H1YG (Office Product)
This product is very refined and if it were not for the difference in labeling you would not recognize them from the originals.
