  1. What exactly are 3M™ Diamond Grade™ Ship Board Letters?

    3M™ Diamond Grade™ Ship Board Letters are a type of adhesive backed lettering made from high-performance reflective material that is specifically designed for use on ships and other marine vessels.

  2. Can you tell me more about the specific product code - 3MNCHAR-2B2, 3975 Blue, "2", 2 in, 10/Package?

    This product code corresponds to a set of ten blue number '2's that are two inches tall. They have adhesive backing which allows them to stick securely to any surface (even when wet) and they're made from highly durable materials suitable for outdoor use even in harsh environments.

  3. How long will these letters last before needing replacement?

    The lifespan of these individual letters will vary depending on many factors such as environmental conditions (UV light exposure, salt water resistance), frequency of cleaning and maintenance work performed onboard. Typically though customers can expect several years of service life from each letter.

  4. Can I order letters with my own custom colors or designs?

    Yes! We offer an option for full customization with our 'Diamond Grade Custom Shapes' program allowing you to create your own unique identification marks with your company logo or colors etc. Please reach out directly if this is something you're interested in.
