Selling computer replacement ink cartridges for B-51, combo pack of 4 (Cyan, Magenta, Yellow & Black). Package has never been opened. Bought a new printer and can no longer use these cartridges. B-51C, B-51M, B-51Y and B-51BK. First find out if these cartridges are compatible with your printer. The box on the right of the picture is the one I'm selling. Disregard the date on the photo, it got stuck on the camera. Date I'm placing the Ad is 7/22/23.
