Gusseted sides expand with your project needs. 2" expansion holds up to 500 letter-size sheets. Reinforced, full-length top tab on back cover provides ample room for labels or handwritten titles. File jackets are made of heavyweight, 11 point manila stock and made with a high percentage of recycled material.
