Get ready for your school's science fair with one or two Beaker Cluster Yard Signs. Mix and match the yard sign with other number, letter, and symbol yard signs (not included) to create one-of-a-kind outdoor messages. Display the science-themed yard sign on any of your school's lawns--it will really have an impact parents, students, passersby, teachers, and more. Made of a sturdy, plastic corrugated material, the Beaker Cluster Yard Sign measures 20" high x 23" wide and includes 15" wire stakes for easy display. The material is both water-proof and weather-resistant, so the yard sign is sturdy enough to withstand most types of weather. Use your Beaker Cluster Yard Sign(s) for science fairs, science club, graduation, and more. NOTE: A minimal amount of assembly is required. No set-up charge!
