This refill kit comes with 120ml of each color (120 ml Black ink, 120 ml Cyan ink, 120 ml Magenta ink and 120 ml Yellow ink). This refill kit is equivalent to 8-9 cartridges per color! That's a total of about 40-45 cartridge yields all in this refill kit!

If you had to buy each cartridge separately, you could spend over $600 for original cartridge brands, or over $300 for compatible cartridge brands.

Remember, the ink in this refill kit is UV resistant and matches the OEM quality in both quality and page yield.
