These Black and White Number Six Yard Signs are an easy way to help your elementary school to create "custom" outdoor messages. These exclusive number yard signs are made of a sturdy, plastic corrugated material and are available in 24" high x 18 1/2" wide and 36" high x 28" wide sizes; both sizes include 15" wire stakes for easy display. Mix and match these black and white sixes with other Number, Letter, or Symbol Yard Signs (not included) to create a variety of outdoor displays, like calendar dates, holiday dates, countdowns, graduation, and more. Each number comes already die-cut--all you have to do is push the wires into the number and then push the entire number/wire a few inches into the ground. NOTE: The plastic corrugated material of these Yard Signs is water-proof and weather-resistant, so it is durable enough to use in almost any type of weather. NOTE: A minimal amount of assembly is required.
