Heavier than standard poster board, the Formit Heavy Duty Poster Board holds its shape whether it's propped up at a science fair, mounted in a storefront window, or pinned to a classroom wall. The extra rigidity means less warping, less flopping, and a cleaner finished look — so your project looks as good standing up as it did laying flat. The bright white surface takes markers, paint, and printed labels evenly, giving you a crisp, professional result every time. At 22" x 28", there's plenty of space to work with for school presentations, business signage, event displays, or creative crafts. Great for: School projects & science fair displays Presentations & tri-fold boards Signs, banners & event displays Arts, crafts & DIY projects.
