Review on 6 Pack SP-700 Black and Red Printer Ribbon Ink Cartridges - Compatible with Star SP-700BR, RC-700BR, SP-712, SP-742 POS Printer Ribbon by Cory Jacobson

I bought a box from this seller when there were only two left. When I ran out of the other two I replaced them with one of the ribbons from this box, the ink looked great for 5 tickets and then quickly faded to the point where the tickets weren't printing all the way through. I thought it might just be a bad ribbon so I replaced it with a new one from the same box, SAME PROBLEM!
