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 Robert Ryokan

**UPDATE 09/2020: The last two black PGBK cartridges have clogged my machine and cleaning the printer thoroughly is becoming too expensive. No problem with C/M/Y. I've had my Canon TR850 for four days now and I'm already out of starter ink! Glad I ordered this replacement set. My machine accepted the cyan cartridge and immediately recognized it as a used Canon cartridge. The print color looks the same as with genuine Canon inks. Happy with the quality and particularly pleased that it's half the price of Canon. I hope the XXL cartridges really last longer. Will have to wait. The box was mailed in a padded envelope for protection.** UPDATE
