Ink cartridges for Canon, PGBK. I am selling these because I mistakenly purchased the wrong model. One of the two cartridges has had the film removed, but is unused. The other is unused and still has the film on. These were purchased on 2025/11/04. - Model: BO-320PBK - Compatible models: MP500 MP600 MP700 MP730 MP740 MP750 MP780 MP790 MP830 MP837 - Color: Black - Quantity: 2 Thank you for looking.
