The Canon GI-50M is a substantial sized magenta ink bottle with a full 70ml of quality ink. Compatible with the novelly designed Canon Pixma G6050 (to name just one machine) the 3404C001 offers astounding economy for a genuine product. Offering you an estimated 7,700 prints from each bottle, the Canon 3404C001 comes highly recommended by us and represents changes in the printer industry that we fully support. Despite its inherent reliability and the quality of the manufacturer, each GI-50M comes guaranteed by Canon directly.
