Internet shipping labels are ideal for use with stamps.com, ups.com, usps.com and other online shipping websites. Bright-white label stock produces sharp text and vivid bar-code images. Each sheet includes two labels. USDA Certified Bio Preferred labels are 100 percent tree-free. Instead of trees, they are made from sugarcane bagasse fiber and other easily renewable, bio-based agricultural waste. Archival safe, acid-free labels won't become brittle or yellow over time. Benign adhesive is safe to recycle yet permanent so your labels stay put. Compatible with desktop dry-toner copiers, laser printers and inkjet printers, labels will not jam or smudge.
