Key specifications
Format: A4 compatible for punched sheets
Ring mechanism: standard four-ring binder
Spine width: 40 mm capacity for punched paper
Cover color: blue
Use: manual insertion and removal of punched sheets
How to use
Open the four-ring mechanism to align punched sheets with the rings, insert pages carefully and close the rings until they click to ensure secure fastening. Arrange documents in the desired order before inserting to minimize rework. For thicker documents, check that the total number of sheets does not exceed the binder's 40 mm capacity to avoid stress on the rings or cover.
Usage recommendations
Store the binder upright on a shelf or in a filing cabinet to maintain cover shape and protect the rings. Keep documents punched with standard hole spacing for reliable alignment with the four-ring mechanism. For long-term archiving, periodically check the binder for wear and replace if rings become misaligned.
