We use the Fellowes Bankers box with lid for all of our Invoices, Statements and A/R storage needs. These easy to assemble and stackable boxes are strong and durable and the sustainability makes us confident they will withstand the FCC regulated 2 to 3 year mandated storage time of our tremendously heavy, multi-moved boxes for our 4 radio stations. The high quality materials and maufacturing gives us what we want, when we need it, and is the best value for the money... hands down...
