Precision & Consistency

Undoubtedly, the sign industry’s premium plastic letters are Gemini’s Minnesota® Injection-Molded Letters. As a process, injection molding has been in use as early as the 1960s, with plastics becoming more common after World War II. Made from a renewable resource material Cellulose Acetate Butyrate (CAB), Minnesota Letters are available in 6 standard styles, 45 standard colors and are in stock ready to be shipped in just 1 business day. The smooth returns, razor-sharp edges and unblemished letter faces give them the look and feel of cast metal letters so they’re suitable for any “up-scale” application. Lightweight and easy to install, these letters are more durable than most plastic letters — not only are they able to stand up to the scrutiny of indoor applications, they’re tough enough to withstand the rigors of the outdoors. As such, they’re a Gemini product through and through and come with our guaranteed lifetime warranty.

There are 45 standard colors from which you can choose. All colors are painted except for Black and White. You can so request cutom paint color which is an additional $20/color for matching.
