Our direct thermal labels are made with high quality, bright white paper backed with strong self-adhesive material. The durable waterproof paper creates sharp, clear text that can be used for all of your shipping, labeling, and warehouse needs. Our mail labels stickers are easy to use with the perforated lines, making them an efficient solution for printing multiple labels at a time. Simply peel and stick once they’re created! The unique finish of our self adhesive shipping label set also makes them dirt, dust, oil, scratch, and high temperature resistant so you can confidently mail and ship items. Each paper sticker measures 4 inches in width and 6 inches in height. There’s a total of 500 thermal printer labels included in this pack. Please note that these shipping address labels are only compatible with thermal printers, not inkjet printers. It is advised that you check your printer model for size compatibility.
