The Really Useful Box with 11 litre capacity in clear can be recycled. Made with 100 percent polypropylene, these boxes are constructed for durability and have reinforced sides to increase compression strength so boxes maintain their shape. Totally flat bottom increases rigidity for stability and allows for perfect stacking with or without lid. The lockable lid is secured with two latch able handles to protect contents of the box from dust and water splashes. It measures 4-7/16" x 14" x 18" and is perfect for storing books, catalogs and small office items.
