Monroe Systems for Business CSK5187 Calculator Supply Kit with P51 Ribbon Cartridges

Customers commonly buy ribbons and paper rolls for their calculators at the same time. To make that process easier we have created premium printing calculator supply kits that include six ribbon spools or cartridges, and a dozen of the nicest single-ply paper add rolls you've ever experienced. With the highest standards in the calculator industry, Monroes ribbon cartridges produce the darkest printing black/red ribbon cartridges on the market using our exclusive True Red color. True Red ink is the perfect red specifically made by Monroe, and doesnt have the orange tint you see in watered down versions from other brands.

Our ribbon cartridges have the highest possible inking degree, and are virtually smudge-free! To maintain the darkest print on your paper tape, we suggest changing your Monroe ribbon cartridges/spools after replacing 3 paper tape rolls.
