Our Broad Posca Water Based Markers have an odorless formula that's fade-resistant, water-resistant, quick-drying and won't rub off the windshield. Even wipers don't remove the writing, and yet it easily removes with a razor blade scraper. Posca Broad fluorescent markers will not "ghost" on the windshield. Water based fluorescent markers are easy to use with the depress and release valve action. Each Broad marker has a ¼" broad tip. Save by ordering the kit of 6 markers (2 of each color), sold separately as P1400 KIT.
