Genuine 4-color ink cartridge set, compatible models are XK100, XK110, and XK500. - Model: N21, N20 - Colors: BK Black, Y Yellow, C Cyan, PGBK Photo Black - Compatible models: XK100, XK110, XK500 - Made in Japan - 4-color ink cartridges Thank you for viewing. I purchased this set in a box, but I only used the magenta cartridge before my printer broke, so I'm selling the remaining ink cartridges as I've bought a new printer. This listing is for the 4 cartridges: BK Black, Y Yellow, C Cyan, and PGBK Photo Black. When shipping, I will remove the cartridges from the box and send only the cartridges themselves.
