Canon GI-21 Cyan Ink Bottle MegaTank Printers

The Canon GI-21 Cyan Ink Bottle is a genuine Canon consumable designed for the MegaTank line of continuous ink supply printers. Unlike traditional cartridge systems where ink runs out after a few hundred pages, a single GI-21 bottle delivers up to 7,700 pages of vibrant cyan output — making it one of the most cost-effective printing solutions available. The bottle features Canon's specially designed nozzle that fits securely into the MegaTank reservoir opening, allowing you to pour ink smoothly without drips or spills, even if your hands aren't perfectly steady.

Compatibility spans a wide range of Canon MegaTank models including the PIXMA G1220, G2260, G3260, G1230, G2270, G3270, G4270, G3290, and G4280, making it easy to find the right ink regardless of which MegaTank printer you own. As a genuine Canon product, the GI-21 is formulated to work in perfect harmony with the printer's ink delivery system, ensuring accurate color reproduction, sharp text, and reliable performance over the life of the bottle. For users who print frequently — whether documents, school projects, or color-rich presentations — the GI-21 Cyan ink bottle turns what was once a recurring expense into an occasional, affordable purchase.
