5,000 Label Outfitters® 1.5 x 1 Inch Waterproof Barcode Labels - Laser Printable Vinyl Stickers for Outdoor & Industrial Use - Weatherproof Labels for Inventory, Shipping & Asset Tracking (100 Sheets)

Good item. These stick to a wide variety of surfaces, including poly zip bags.One note: If a partial sheet of labels is printed, running the sheet through a second time to print more labels usually results in smudged printing, occasional loose labels, and difficulty peeling from the backer sheet. The answer is to try to always print full sheets of labels.If the laser printer or printer driver has a setting for thick paper or labels, that reduces jams. All labels, of any type or brand, will jam occasionally!We've re-ordered from these several times. Shipping isn't quite as fast as Prime, but both the vendor & product have been reliable over several years.
