Another pen show find is the Nakabayashi Logical Prime notebooks. These are softcover notebooks are stitch bound with a bookbinding tape over the stitches to reinforce.
There are a variety of interior paper options (Point, Graph, 7mm Lined and 6mm Lined) and the notebooks can be found around the internet in a variety of sizes. Yoseka Stationery stocks the Logical Prime notebooks in A5 size ($6 each).
The more unusual B5 size (6.9″ x 9.8″ or 176 x 250mm) was picked up from a vendor at a pen show. Which show? Maybe the California Pen Show. Which vendor? Taccia but they don’t list these notebooks on their web site.
According to the Nakabayashi Global web site, the Logical Prime notebooks are only available in A5 and B5 sizes though in the US market, you are more likely to find an A5 notebook than the larger B5.
All the internal rulings are in a fine dark green line. At the top or each page is a space for writing a title or description and date.
What’s really interesting about these notebooks is the unusual ruling options (I didn’t get one of the standard grid notebooks because after seeing the Point and Lined, the graph was just ho-hum). The Ruled options, both 6mm and 7mm actually feature two additional light dotted lines between each solid rule creating guides for much smaller increments. There are also dotted vertical lines at the same interval as the ruling so the paper can be used as graph if you want or need it to do so. The multiple horizontal lines would be great if you want to practice your handwriting or calligraphy.
At the top and bottom of the page are dots and tick marks indicating the center of the page, 1/3, 1/4 and so on. If you were wanting to grid something out on a page, these marks will help you maintain consistency from page to page. If you were to use these notebooks for bullet journaling, this would help to divide the page for week-on-two-pages, making a monthly overview calendar, etc.
The paper is a soft cream ivory color, not bright white.
There is not a huge difference, obviously, between the 6mm and 7mm lined paper but I know folks have clear preferences. When I was testing the paper, I thought I preferred the 7mm lined because I had a little more space but I was really jumping between the margins in a weird way so I think the 6mm is a bit better for my tiny handwriting.
Then there was the Point style which has dots spaced really far apart. On the back cover it says “12x15pt” which I think is 12mm dot grid (approx 9/16″) or thereabouts. That’s some pretty big grid!
I feel like a grid of this scale is a good compromise for someone who might want blank but needs a little guidance.
Did I mention that this paper shows sheen? Probably should have mentioned that sooner. So, good quality paper, unusual ruling options, and its affordable? You should probably stock up now. I don’t think you’ll regret it.
