Atr our company we use the red color of these folders to denote files that must remain in the office. This makes them easy to spot if they are in someone's possession or headed out the door. These files have held up to the rigorous use that we put them to at our business. We find that the color coded folders help keep things easily organized at a glance. The larger the quanitity the better the price. The taples brand has always been our best choice for quality at a very reasonable price point.
