#3 Size Inspection Arrows (most common size) 1/4" x 3/16" Inspection arrows are used to recall areas for repair, quality control inspections, or marking drawings and instructions. The arrows can be removed or repositioned without leaving adhesive residue, and they won't fade lift, or become brittle. Labels are packaged in flat envelopes (sheets) of 1000 per. Color coding systems can easily be established to identify different types of action to be taken.
