The Dylusions Paint Pens only need to be primed if there is no paint in the small chamber above the tip. Once a pen becomes over-primed, do not prime it again. Clean-up the tip with a baby wipe, and while holding the pen upright, depress the tip on the surface, hold it there for at least 30 seconds, or until you can see paint coming from the tip when it is moved on the surface.* This should allow you to write with the pen.
Always use the pens in an upright position and not at an angle. The pens have a much smaller tip than other types of paint pens, so the paint needs to be flowing in the direction of the tip. Once the pen is tilted, even slightly, this may result in skipping. This is especially important when using the white paint pen, as the pigment makes the paint slightly thicker. It is also helpful to use the cap when letting the pen sit, even for a minute.
There may be a slight “skin” of paint on the tip the next time you go to use it. As long as there is paint in the small chamber above the tip, there is no need to prime the pen. Simply moisten the tip with a baby wipe (or the tip of your finger and follow the suggestion above*).
Finally, when you have finished using a pen, clean-up the tip with a baby wipe, tightly secure the cap and store it horizontally.
