Canon CLI-42 Professional Ink Set with Multiple Colors

High-quality Canon ink set for PIXMA PRO-100. Includes eight vibrant colors for professional printing.

The only ones that are missing are the yellow and the gray and the magenta so you get almost 2 full complete sets of the ink for the Pima pro 100. I have stored these in air-conditioning. I’ve had them for years. I couldn’t tell you how long
