If I sold felt tip and paint stick pens I would surely want to make it easy for my customers to try out. Though frowned upon in the food business, sampling in this retail category is a near necessity. This All Wire Pegboard Fixture provides a sloped landing area to mount Scratch Pads for testing (pad missing in photo).

A great idea to satisfy the need, but might you have ideas for a better, simpler design?  If so leave a comment, or submit a felt tip sketch of your own for me to publish in your behalf. Fixture fame could be just around the corner for you.  Look here for some custom creations my company has been involved in recently.
