These labels are compatible with popular thermal label printers for a polished, professional look. Packed in a secure bag to protect from light and ensure optimal performance, these labels come packaged in rolls, making it easy for you to print one label or one hundred. Permanent adhesive helps them stick and stay in place. Labels are great for addressing envelopes, labeling file folders and identifying product samples.
