Notes File Jackets eliminate messy scribbles or sticky notes often placed on the outside of files. Keep track of information directly on the pre-printed lines on the front and back sides of the jacket. They expand 2" for added capacity. File jackets are closed on three sides for document security and keeping those small incidentals contained. They are great for taking files out of the office. Reinforced, two-ply tabs on the letter-size jackets provide extra durability.
