Wiro Ring refers to a binding method that uses a series of metal loops to secure pages together. The wire is usually made of metal, such as steel or aluminum, and comes in various diameters to accommodate different document thicknesses. This involves punching holes along the edge of the document and then threading a double loop wire through these holes. The offered ring is a popular choice for a wide range of documents where durability, flexibility, and a professional appearance are desired. Wiro Ring is available in various colors and finishes, allowing for customization to match the document's aesthetic or branding requirements.
