Reader board letters are individual letters made to fit into a sign board with grooved tracks. These letters are often found on roadside signs, movie theaters, churches, and other establishments that need to convey a short term/specific message to a large group of people.
They come in a wide variety of sizes, fonts, and colors, and are made from a range of materials like plastic, acrylic, and metal. They are easy to change out and rearranged to form new messages. They are a great way to catch the attention of passersby and communicate important information to customers.
