With functional good looks, the ISO organizers have their roots in classic office design but they work all around the home, from desktop to entry table and beyond. Their design and dimensions are derived from international paper standards. US-made of heavy gauge cold rolled steel, they have substantial heft, weighing in at over five pounds. The design is completed with a durable, matte powder-coated paint finish and thin cork bottom cushion to keep them in place and protect the surface they sit on.
