If you are working on several projects at the same time you might need several refills to your notebook. Maybe you want to keep your private notes separate from your work notes.
To organize your different projects and different kind of paper in your notebook you can use the binding rubber bands.
Inside the package there is a small guide (English text provided), which helps you step by step with adding one or two refills.
