Coroplast signs are great for temporary outdoor signage like yard signs, political campaigns, real estate listings, business advertisements, or for indoor signage like menu boards. They come in a variety of sizes and can be printed full color on one or two sides. They are completely waterproof, and resistant to hot and cold weather. They can last 1-2 years outside and up to a decade inside. Our coroplast yard signs are 18" x 24" and come with a metal stand or we offer metal frames to display your sign.
