I have a large project to get my home office organized 3 tab folders help me address most of my organizational needs. Additionally these folders are sturdy and accommodate frequent handling.
I would only use heavy-duty folders like these for client files. I move them in and out of file drawers often wrap them with a rubber-band and they bounce around on the car seat and between the seats. Flimsy file folders would never be adequate. These are perfect and the colors are bright and refreshing.
I really like these heavyweight folders. The tabs do not bend or get flimsy and last longer and keep my files looking neat and fresh. I recommend spending the extra money for the heavyweights.
