キヤノン PFI-1000 GY LUCIA PRO グレーインクタンク（80ml）

I was a little worried about the price per cartridge, but this 80ml tank lasts a lot longer than the standard sizes. The pigment-based formulation gives my black-and-white prints a really deep, neutral gray that I haven't been able to get with other inks.

The gray tones in my prints are noticeably richer and more neutral since switching to this ink. It handles detailed black and white photos beautifully, and the pigment really does feel like it will last for decades. I’m glad I grabbed this size for my print runs.

Didn't expect the 80ml volume to last this long, but my monochrome prints are still coming out with that deep, neutral gray I was hoping for. The pigment base gives me peace of mind knowing these prints won't fade for a very long time.
