Bantex A4 Insert Binder 3D Ring 50mm Black Box of 12

A 50mm ring binder typically accommodates approximately 450 to 500 sheets of standard 80gsm A4 paper. Actual capacity may vary slightly depending on paper weight and whether dividers or pockets are included in the binder.

A 3D ring mechanism uses three rings spaced along the spine rather than two, which distributes the load of the pages more evenly. This reduces page curl at the spine and keeps sheets lying flat when the binder is open, making it easier to read and write on documents.

Yes. The binder has a clear overlay on the front cover, back cover, and spine, allowing you to slide in a printed or handwritten insert for easy identification. There is also a clear horizontal pocket inside the front and back cover for additional inserts such as business cards or reference sheets.

This listing is for a box of 12 Bantex A4 Insert Binders in black. Each binder has a 50mm 3D ring mechanism, clear front and spine overlays, and internal pockets. The price shown is for the full box of 12.

Yes. The polypropylene (PP) cover construction is more resistant to warping and cracking than board-covered alternatives, making it a practical choice for binders that are pulled from shelves and handled regularly throughout the working day.

Yes. The binders accept standard A4 ring binder accessories including clear pockets, dividers with tabs, and multi-punched sheet protectors. Ensure any accessories are punched or designed for use with a 3-ring binder rather than a 2-ring lever arch format.
