The package includes 30ml black, 30ml cyan, 30ml magenta, 30ml yellow, 4 syringes, 1 thumb drill and the illustrated refill instructions. Notes: (1) If the cartridges need to change ink from dye ink to pigment ink, or from pigment ink to dye ink, it's better to do some clean for print heads at once after installing the new ink. That will prevent these two types of inks from bonding together and clogging the print heads.
