The metallic pens do work on canvas however, the texture may present a challenge. Unlike the Pitt Artist Brush Pens, this nib is a 1.5 mm which is harder than a brush and does not flow the same as the brush pens. You may experience skipping if the canvas has a lot of texture. We suggest conducting a test to make sure you are achieving your desired result.  Canvas texture and different types of canvas primers can impact the flow of the ink.
