Write-on, color-coded tab accepts markings from pencil, ballpoint pen or permanent marker for easy identification. Folders open on two sides for easy access and feature reduced glare. Unique, gusseted corner design allows folders to expand to hold up to 100 pages. Folders are designed for letter-size document storage.
