Improve the visibility and efficiency of caution signs, bar-code labels and more with these Reflective Sign Labels. Created with a strikingly eye-catching, retro-reflective finish, glass bead technology is used to directly reflect light back at the same angle it's received. These reflective labels are perfect for improving the visibility of signs in low-light situations and creating long-range bar codes that can be scanned from further distances. Durable polyester material is UV-resistant, chemical-resistant, water-resistant, abrasion-resistant and tear-resistant. Great for both indoor and outdoor use, these permanent adhesive labels last up to 2 years outdoors. Begin creating your own high-visibility, custom reflective signs and labels with free online templates and a standard laser printer. Each sheet includes four labels (3-1/2" x 5").
