Using a binder instead of a regular notebook has its advantages: you can easily change the order of your papers, as well as add or remove however you want. The disadvantages are usually obvious: they are large and cumbersome. This is where Kokuyo's Smart Ring Binder comes in: they are incredibly neat and don't take up much more space than a regular notebook.
The binder is also equipped with practical pockets to store, for example, loose leaves, business cards or stickers. The binder also comes with instructions and 10 sheets of Kokuyo Campus Loose Leaf Paper Sarasara with dotted lines.
The binder holds up to 25 pages.
More refills can be found here.
Instructions: Push the plastic bar down to open the rings. To close the rings, it's enough to pinch them together with your fingers.
The binder has 20 rings.
