Never opened 2-pack of genuine Canon Pixma black ink cartridges. It is 210XL for printer models: mx420, mx360, mx340, mx320, mx410, mx350, mx330, mp495, mp480, mp250, mp490, mp280, mp240, and iP2700.
compatible with all those models. sells for $70 at Wal-Mart.
I bought these for a printer I just got rid of. I can throw in an extra one (new) for $10.
