Over 90 years ago, Top Flight began as a one-machine paper box manufacturing plant, then known as Atlas Paper Box Company. Founded in 1920 by H.T. Robinson, E.W. Macmillan, and the brothers E.D. and H.T. Bryan, Top Flight is still owned and operated by the Robinson family today-and is still committed to strong core values and quality paper products. Top Flight Boss Flexible Binders are a simple, economical choice perfect for home, school and office use. Each poly binder features three rings with a 1 inch holding capacity. The durable poly material was built for frequent use. It won"t crack, rip or tear and is tough enough to handle rough use and resist splits or tears. The matte finish on the covers provides a professional appearance. Boss Binders are available in an assortment of vibrant colors to help you stay organized and color code your work. Top Flight has a rich history of success in the paper industry. While maintaining exceptional customer satisfaction, we have consistently built our product lines over the years to continue to offer the most innovative paper products available.
