These Prom Letters are made of sturdy cardboard but they look like natural wood without the heft and price of the real thing. Use the light-up letters as a fun focal point for your rustic or garden Prom theme. The kit includes the printed cardboard letters and light strands with sockets and 25-count bulbs. The letters range in width from 20" to 33;" each measures 35" high x 9" deep. Assembly required.
