I've changed my printer so these are surplus to requirements. They're not branded but I always found them reliable. Not a full pack - there are:
2 x C521 Y (cyan)
2 x C 521 B (black)
They're all still sealed in plastic although I've had them a while now so some evaporation may have occurred.
They fit all the models specified on the pack (see picture)
Collection by arrangement from Piccotts End
Printer cartridges for Canon Pixma models (Old Town HP2)
