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 5 gridded pages.
The binder holds up to 25 pages.

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.
