With a 1" expansion, these manila file jackets are designed for storing charts, photos and bulky documents that do not fit traditional file folders. Letter-size file jackets are closed on three sides for document security. Full-height sides keep materials from slipping out, making this a great file for taking documents out of the office. Single-ply, 1/2" high straight-cut tabs are perfect for frequently used files. File jackets are made from 11 point stock and are equipped with rounded top corners on back panel and thumb-cut in front panel.
