NEOPlex 24" x 36" Black Corrugated Plastic Replacement Panel for Sidewalk Sandwich Board A-Frame Signs

This Coroplast panel is made of corrugated polypropylene material. This construction is very similar to the way heavy cardboard box material is made, but with polypropylene (plastic). It is 100% weatherproof, lightweight and a very tough ridged material. Uses include: laminating, taping or tacking posters or other fliers. It also works great for vinyl lettering or as a marker board when used with our liquid chalk markers. This panel is reversible, so you always have a fresh side.
