Ro-Biki Notebooks are unique for many reasons. First, they are an unusual size: 3.6 by 8.3 inches. Second, they contain paper made exclusively by the Yamamoto Paper Company. And third, they are offered with intriguing grid types, including 2mm squared grid and 5mm reticle.
I'm reviewing the Ro-Biki 2mm Squared Notebook. It has a russet-colored kraft paper cover that is waxed, giving it a lovely sheen, and it only gets better with age. The notebook features rounded corners and a chain stitch binding. The chain stitch offers much more flair than the usual pamphlet stitch. Plus, it makes the notebook extra sturdy. You can fold the notebook over on itself without worrying about any paper falling out or damaging the binding.
