Along time ago, I had a Lexmark printer that required small cartridges which had to be replaced at $50.00 or more each. My Cannon Printer using the 137 Black toner lasts for months of moderate use or for many weeks of heavy use such as printing a book of 40 pages per copy. This is a significant saving.

I have been buying these toners for years. Sometimes "Compatible" and sometimes "Moustache". Quick and efficient delivery. Excellent price. Print quality is excellent as always. A few years ago I purchased a cheaper brand on Amazon, but the print quality was awful. I remain a loyal and grateful client !!!

Yep

works as expected, would buy again
