Because they will weaken if wet, we recommend a fast drying ink to penetrate the surface quickly and efficiently. We sell a great number of valve controlled ink markers in our arroMarker® product line that are suitable for paper and cardboard. We also distribute a great variety of capillary action ink markers from Sharpie®, Artline®, Sakura®, and Avery®. High quality ink markers are you best bet for getting a uniform mark that will dry fast and not create puddles on your paper/cardboard.
