Review on 🖨️ GREENBOX 15 Pack Compatible Ink Cartridge Replacement for Canon PIXMA Printers - Canon 280 281 PGI-280XXL CLI-281XXL: TR7520 TR8520 TS9120 TS6120 TS6220 TS8120 TS8220 TS9520 TS9521 by James Lozoya

These cartridges work great. The only problem I had was that they leaked horribly when installed. I've used other brand aftermarket cartridges for many years, but I've never had my hands leak from simply inserting them into the printer before. I think next time I will buy from another company. Updated 4/16/21. At first I thought they were fine, but after sitting in the printer for a few months they started leaking and clogging. I am getting illegible printouts. After two head cleanings, we finally took out all Greenbox ink cartridges and replaced them with original Canon cartridges. Now my printer is working again.
