Hi Tim - thanks for your question. The pens are specially formulated for writing on glass and glazed surfaces. I personally use them on my plastic containers for marking food or meal items, however they are not specifically formulated for use on plastic so would require your testing it out on the particular item to make sure the ink wipes off to your satisfaction. :) Gina
