Our lettering and numbering decals are available in a variety of practical sizes ... whether you are applying labels vertically to fiberglass marker posts, or numbering campsites, or displaying miles to a trailhead.  Our letters/numbers are offered individually, in strips, as refill pages, or in deluxe kits. These decals are made from high-quality 3M™ materials and under normal conditions should last from 7 to 10 years. Reflectivity grades are shown for each product and range from Engineering grade (EG) to High-Intensity Prismatic (HIP). We use a special translucent ink which allows the reflective base material to shine through.
