Our Jumbo Posca Water Based Markers have an odorless formula and are fade-resistant, water-resistant, quick-drying and won't rub off the windshield. Even wipers do not remove the writing, and yet it easily removes with a razor blade scraper. Jumbo Posca Markers will not "ghost" on the windshield and they are easy to use with the depress and release valve action. Each marker has a 5/8" extra bold tip. Save money with a kit, which includes 6 markers (2 of each color) and is sold separately as part# P1500 KIT.
