As the inventor of the commercial calculator in 1912, Monroe has earned the trust of Fortune 500 companies, non-profit's and government agencies, including the likes of NASA. 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 developed the most convenient calculator ribbon. They created the first-ever cartridge containing a ribbon, which provides you with the easiest installation. Don't let ribbon ink get on your hands, use Monroe's high-quality ribbon cartridge instead of ribbon spools. Having the highest standards in the calculator industry, Monroe produces the darkest printing black/red ribbon cartridges on the market. Monroe pushed every envelope when designing a ribbon with the highest possible inking degree, and eliminated the risk of ink smudges. Monroe requires their factory to use a true red ink that is extremely rich in color and used specifically 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.
