PaintScratch.com founder Collin Harris shows how to use touch up paint pens, and says the following in this video:

Here is our touch up paint pen with Silver Metallic Clearcoat for this 2010 Toyota Prius. To start the flow on this paint pen, you simply depress the tip just a little bit. I like to use a plastic container like this and just get a little bit of paint, wipe it down a little bit. Go to your scratch and just put a little bit on with the paint pen. Don't try to get it too thick. You can go back to your reservoir on your cap with the tip of your paint pen. Just get a little bit of touch up paint in the scratch. Apply the touch up paint to your car 2-3 times.
