Key specifications
Format: A4
Ring type: 4 metal rings
Spine width: 30 mm (capacity about 200 sheets depending on paper weight)
Cover color: black
Intended use: punched documents and report organization
How to use
Open the ring mechanism, insert punched pages or plastic sleeves onto the rings, then close securely to keep documents aligned. Use the outer cover for labeling either with a printed spine label or a marker on the surface to identify contents. When removing or rearranging pages, open the rings fully to avoid bending paper or overstressing the mechanism.
