What to know before buying
- The listing describes five bottles and the package breakdown as two black plus one each of cyan, magenta and yellow, but its yield text gives estimates per black bottle and per colour bottle without clarifying whether the black estimate applies to each of the two bottles. The title also mentions G3270 and G3290 as product identifiers as well as printer models, so confirm the selected listing is for the intended printer and pack. Colour yield is stated at 5% coverage on A4 or letter paper under an ISO/IEC standard.
Who is it for?
A good fit for
- Owners of a listed Canon G-series printer who want compatible GI-21 refill bottles and need an additional black bottle.
- Buyers who can match their exact printer model to the listing's compatibility list.
Less suited to
- Owners of printers not included in the stated compatibility list.
- Buyers seeking original Canon-branded ink rather than compatible refills.

The supplied aggregate ratings lean positive, with most ratings in the four- and five-star categories, but there is also a smaller share of lower ratings. Without written feedback, the reasons for those ratings are unknown. Treat the ratings as limited context rather than evidence of ink performance or compatibility. The printer-model list and conditional yield claims are more directly useful when deciding whether this refill set suits your setup.
