Ring binder Oxford 100421115 A4 Black Round ring Presentation

The Oxford 100421115 A4 ring binder in black is designed to store and present A4 documents neatly. Its round ring mechanism enables smooth page turning and secure sheet retention, while the compact dimensions (235 mm width, 20 mm depth, 310 mm height) keep the binder slim and easy to handle. The black cover offers a professional appearance appropriate for meetings, presentations, and organized filing.

Its compact depth makes it suitable for storing a moderate number of sheets without taking much shelf or briefcase space.

How to use

Open the round ring mechanism by lifting the ring release, insert punched A4 sheets onto the rings, and close the mechanism until it clicks to secure pages.

To add or remove pages, open the rings, adjust the contents as needed, and close the rings to resume normal use.

Usage recommendations

Store the binder upright on shelves to avoid warping; avoid overfilling beyond the recommended depth to prevent strain on the ring mechanism. Use standard A4 punched pages for best fit and consider dividers for organised sections.
