Spine width: 50 mm capacity for documents
Cover: durable board material with black finish
Binding mechanism: ring binder system for punched sheets
Material certification: FSC-certified board
How to use
Open the ring mechanism and insert punched A4 sheets aligned with the rings. Close the rings until they click or align securely to prevent pages from slipping. Store the binder upright on shelves or flat in drawers; avoid overfilling beyond the 50 mm capacity to maintain the mechanism’s function and the cover shape. For archiving, label the spine or add a spine insert if available to identify contents quickly.
Usage recommendations
Handle the binder by the spine or edges to reduce wear on the cover. Keep the binder away from excessive moisture and direct heat to preserve the board material. Use hole-reinforcement labels for frequently turned pages to extend longevity of documents.
