You get a total of five colors among four folders, but you have eight combinations with the reversible design. Folder colors are green/yellow, pink/green, orange/pink and blue/yellow. Turn the folders inside-out if you need to change-up the order of your system for convenience. Standard 11-point construction works best for ordinary computer paper, glossy brochures and photos. Each folder can expand to hold up to 150, 8.5" x 11" pages, which amounts to a medium-sized report. These folders work well for employee files, daily transaction records, everyday financial statements, signed documents and printed correspondence. Staggered tabs let you label each folder appropriately, including hand-writing words, letters or numbers on folders. Alternatively, go for a professional look by printing customized labels on your computer. The expandable filing system gives you complete freedom to organize your desktop, file cabinets, archival storage or employee documents.
