Sturdy Pressboard Expanding File Folders are ideal for active, daily use and expansive filing jobs. Gusseted spines allow the folders to expand to accommodate larger files and are reinforced with rip-proof tape to prevent splitting even when the folders are loaded to capacity. An under-cut front cover helps the back cover's tab stand out, making both labeling and in-cabinet referencing easier. Durable, 25-pt. pressboard withstands heavy use. File Folder Size Type: Letter; File Folder Color: Green; Color Family: Green; File Folder Material: 25-pt Pressboard.
