Dimensional Letters are individual letters and numbers formed out of flat cut out acrylic or aluminum, fabricated metal, cast metal or plastic. They have a 3-D, dimensional look that lends depth and character to your sign. Non-illuminated, they are most commonly used in lobbies, stores, offices and interior applications but are durable outdoors as well. Available in a rainbow of colors, and most basic fonts, Dimensional Letters are an excellent solution for a classy, professional looking sign.
