What makes this writing material unique is that it provides the best writing experience combined with excellent erasability. Additionally, the notebooks have the Unbind & Click system, allowing you to easily expand, move, or remove pages. This allows you to effortlessly create your own unique notebook. The specially designed Core pages, known for their high quality, provide a writing experience similar to regular paper, and the notes dry within seconds. Once your text is dry, it can only be erased using the back of a pen, the eraser cloth, cleaning sponges, the cleaning set, or a dry/damp cloth. You don't have to worry about smudges when writing notes in your notebook.
