Okidata Black Nylon Ribbon for Microline 320/321 Printers (5/6" x 2 Yards) - High-Quality Replacement Ink Ribbon for Receipts, Labels & Business Forms - Perfect for Retail, Hospitality & Office Use

I had purchased this item thinking it was the okidata ribbon but when I had recieved it, it was an off brand. They last about 1/5 the amount of the way that the okidata ribbons would.
