Environmentally friendly file labels are 100 percent tree-free. Instead of trees, they are made from sugarcane bagasse fiber and other easily renewable, bio-based agricultural waste. Bright-white, mailing labels are guaranteed not to jam. Each 2/3″ x 3-7/16″ is sized for 1/3-cut tabs. Acid-free labels won’t yellow for long-lasting use on your file folders. Self-adhesive is permanent so your labels stay put. Labels are compatible with copiers, laser printers and inkjet printers. Each sheet includes 30 labels.
