Each yard letter measures 18” tall and can be seen easily along any roadside, driveway, or yard. The steel stakes that come with the birthday letters help make for an easy and stress-free set up; our signs are also weatherproof, ensuring they last you through not just the spring and summer, but the fall and winter seasons as well. These outdoor yard decorations are colorful and stand out, being made from durable corrugated plastic for long-lasting use and reusability for your outdoor celebrations or birthday parties. We currently offer messages for many occasions and events including graduations, anniversaries, birthday celebrations, gender reveal, baby shower, military welcome home, holidays, retirements, and much more
