Gemini Pronto™ Changeable Copy is a cut above traditional saw-cut changeable copy. Made from a rigid and durable injection-molded blank, each panel is molded with a small raised edge on the back designed to prevent scratching as the letters are moved in and out of the Pronto track, extending the useful life of each letter. The molded-in feet keep debris and ice from interfering with the change out. Best of all, eco-friendly Pronto letters use highly durable UV inks with no VOCs. With Pronto, there are no harmful emissions created during our manufacturing process.
