Adhesive markers are an essential tool for clearly identifying and sequencing blood spatters, bullet holes and other physical evidence at a crime scene. These markers offers a better way than the conventional number booklets. These adhesive markers come on individual sheets in refillable kits, eliminating the problem of running out of lower numbers and wasting higher ones. In addition to numbers 0 to 9, we also provide letters, blanks and arrows. This variety makes it possible to make multiple digit numbers and number/letter combinations. 20mm Scale on each marker adds perspective to photographs. Each marker is 1” x 1 3/8” and comes on a sheet of 25. Non-glare matte finish eliminates reflections in photographs. Each option comes with 50 labels each of the numbers and/or letters; blanks with scale and arrows.
