The wire-O binding uses double loops made of wire, which makes it sturdy and long-lasting. This is a perfect solution for documents that someone will often write in, like reports, brochures, notebooks and handbooks. It can stay open for prolonged periods and can be opened to a full 360 degrees. The Wire-O binding gives users sleek and professional-looking documents with a pleasant reading and writing experience. It will not be distorted after being used for a long time. The wire is strong enough to hold different materials like plastic, board and paper together, and it is suitable for both small page count documents and those with 400 pages. Make sure your design doesn't have graphics that go across the pages when choosing Wire-O binding because the wire will interrupt the design.
