It's black ink. Difficult to get super excited about black ink. It does the job. Ever put the phony ink in your HP printer???? You'll wish you hadn't done that! Stick to the real deal.
I bought two packs of black and a pack of variety color ink enough to printing a few pages I ran out of black ink. I hope the rest of my packages aren't that low in ink.
Black cartridge didn't work correctly. Had to clean heads 3 times before it would print more than 3 lines on test page. Printer recognized it as a used cartridge tho you sold it to me as a new cartridge. The color cartridges were good, no problems with them.
