Genuine OEM Canon PIXMA TR4520 Ink and Supplies

A PG-245XL twin pack for the TR4520 gives you two black cartridges, not black and color. It makes sense when you want a spare black cartridge, but you'll need CL-246 color separately if that's running low too.

Toner Buzz carries genuine Canon PG-245 and CL-246 singles, including XL options, along with PG-243 and CL-244 ink-and-paper packs. Choose XL for more printing between changes, or the black twin to keep a spare on hand.
