AI-generated summary
At £17.62 ex‑VAT, this Canon CLI‑581XXL Photo Blue is the sort of ink cartridge that usually makes sense for small offices or home studios that print a lot of blue photos/graphics and want fewer cartridge swaps. The “XXL” angle is the real value lever: if you’re feeding a compatible Canon printer regularly, you’ll typically get better cost-per-page than standard-size inks and the colour consistency is usually more reliable than going off-brand.
That said, I wouldn’t buy it “just in case.” If your use is occasional (or mostly documents/black-and-white), the ink can be a waste—especially because colour inks can dry out or degrade with long gaps, and you’ll end up paying for ink you won’t use. Also, while it’s listed under toner supplies, this is an ink cartridge, so make sure you’re ordering the right consumable for your printer model—nothing kills value faster than a mismatch. If you tell me your exact Canon printer model and roughly how often you print colour, I can sanity-check whether the XXL size is actually worth it.
