Only the Cyan cartridge has "Product of Japan" on it. The Cyan and Magenta cartridges have no product manufacturing info on the boxes. Not sure if this is a "standard" HP product. Haven't tried to use it yet. Hope my HP printer doesn't reject the 2 cartridges with no manufacturing info. Cartridges are ridiculously overpriced. The 3 cartridges cost more than the printer price I paid for it new.
I ordered these but have not run out of toner yet, I have no doubt they will perform as expected and if they don’t; I have every confidence HP will make it right.
