Highly recommend
Color: 2 Black,1 Cyan,1 Magenta,1 Yellow
Worked perfectly for my printer! The print quality is just as good as the original ink it came with, and the price is much better. Easy to install, no leaks, and looks like it will last a long time.

The bottles are a good size larger than expected and come with an extra black. Easy to fill without any spilling and works great in my printer. I am pleased with the print quality and color. Price is very reasonable for all you get.

It’s just what I ordered! It came very fast and the ink is sealed individually so it should last until I need it! I used the first bottle of black ink immediately! Thank you
