The Avery AV1789 are Paper File Folder Labels that are 5/8" x 3 1/2" - 50 Labels per roll.

The Avery label cassettes offer non-laminated die-cut paper labels with standard strength adhesive. They are great for one at a time label printing when your application doesn’t call for an entire sheet of Avery labels, just a few. Each label prints black letters onto a white die-cut label.  UPC: 012502603016
