Avery TrueBlock Permanent File Folder Labels (model 8366) are bright white, 1/3-cut labels sized 2/3" x 3-7/16" to fit standard file folder tabs. Each pack includes 750 labels across 25 sheets with 30 labels per sheet, providing a generous supply for home or office filing systems.

Avery's TrueBlock Technology completely covers any previously printed or handwritten text underneath, allowing file folders to be relabeled and reused cleanly without bleed-through. The permanent adhesive is engineered to stick securely without curling, lifting, or peeling over time. Sure Feed Technology improves sheet feeding through printers to minimize jams and misfeeds.

The labels are compatible with both laser and inkjet printers, and Avery provides free downloadable templates (template number 8366) compatible with Microsoft Word, Google Docs, and other popular word processors at avery.com/print. Labels are acid-free and smudge-resistant for long-lasting legibility. The product carries FSC certification for environmentally responsible paper sourcing.
