If you want the best calculator ribbons you've got them! As the inventor of the commercial calculator in 1912, Monroe has earned the trust of Fortune 500 companies. Even Hollywood has recognized the strength of the Monroe brand as its products have landed on major television networks and hit series including the show Madmen. Monroe's engineers have developed the best available universal twin-spool ribbons for calculators. Monroe pushed every envelope when designing a ribbon with the highest inking degree on the market and eliminated the risk of ink smudges. Monroe has even developed a true red ink that is extremely rich in color and used exclusively by Monroe, unlike the orange tint you see in watered down versions from other brands. To maintain the darkest print on their paper tape, users of Monroe products are suggested to change their ribbons after replacing 3 paper tape rolls. Those who know, choose Monroe. This premium universal twin-spool ribbon is compatible with all printing calculators that take ribbon spools. Brands such as: Canon, Casio, Innovera, Monroe, Sharp, and Victor.
