Typically, a refill kit comes with a cartridge holder, bottles of ink and needles. The exact tools that come with the kit can vary by manufacturer or by which cartridge the kit is for. Some tools are found in all kits because they are necessary to refill, but others, like the cartridge holder or a needle to withdraw air from the cartridge, are optional.The most common refill kits come with either: bottles of black ink for black refill kits or one bottle each of cyan, magenta and yellow for color refill kits or one bottle each of photo cyan, photo magenta and photo black for photo-color refill kits or combination of all colors for combo refill kits. http://www.cheaprefill
