Features of the Campus Smart Ring Binder Slim and not bulky This ultra-lightweight smart ring binder is as thin as a regular paper notebook, so you can carry it around without adding bulk to your bag. Easy to carry around every day! Space Saving The cover features a smart ring and fastener that can be completely flipped over, allowing you to read and write in tight spaces or while standing. Flat open Unlike a traditional binder, it opens flat without hand pressure, so the gap is wide and it's easy to change loose-leaf paper. How to open and close the smart ring binder The ring can be easily opened with a single touch on the top of the binding. The ring can be closed from the left and right with a light pinch.​ Customer Reviews Price Sheets/Total 500 250 100 100 120 Page Style 7mm Ruled Blank/Unruled 7mm Ruled 7mm Ruled 6mm Ruled Writing Style Firm Writing Smooth Writing Smooth Writing Firm Writing Smooth Writing
