Nakabayashi's Logical Air Swing notebook is fountain pen-friendly! Well, my bar for what is "fountain pen-friendly" is pretty low compared to other people. I'm willing to use any paper that at least has Level 0 properties (my made up, personal criteria):
- Ink doesn't feather outrageously
- Ink doesn't bleed through the paper (can use both sides)
- Ink shows some sheen
- Ink shows some shading
There is no Level 2. This is getting into my " I will weigh the tradeoffs" for different contexts/purposes.
- Paper weight
- Ink dry time
- Paper colour
- Notebook design (page count, numbering, ruling, binding, etc.)
The Logical Air Swing Notebook satisfies Level 0 and Level 1 in my personal assessment. I'm not going to get into great detail since there are others who have done paper comparison with a greater degree of control measures.
As a paper/notebook x fountain pen lover, I've referred to John Bosley's fountain pen friendly paper rating list as reference for what fun new things to try out. He also has a good list of fountain pen, ink, and paper basics.
A while back, John reviewed Nakabayashi's Logical Prime Notebook and I ended up looking into their broader Logical notebook brand. They had a notebook called Logical Air Swing Notebook as well. The promo for the Logical Air notebook says that it's especially good for students to be carrying lighter weight paper in their bags.
Somewhat confusing Swing Logical notebook nomenclature:
- Swing Logical Air is 56gsm
- Swing Logical is 70gsm
- Logical Prime is "7% thicker and firmer than standard version" (advertised to be fountain pen-friendly)
- There's also a whole bunch of other names in the notebook line, like Logical Think, Logical Brain, Logical Sport, etc..
Based on the logic (!) above, one might assume that Logical Air may NOT be fountain pen-friendly. It's interestingly close to the weight of many people's fountain pen grail paper Tomoe River/TR (52gsm). I see the value of TR but the dry time is a big trade-off for me.
Since I was making the best of my proxy shopping/shipping from Japan (Buyee), I threw in a A5 Logical Airs 5mm grid ruling into my order (from Fueru's Rakuten) and hoped for the best (they're ~180yen). Months later, they arrived!
I have the green cover A5 5mm square grid notebook with 30 sheets. The cover is a lightweight and flexible cover stock with a bit of a gloss coating.
It's one fat signature, sewn-bound down the middle.
The interior paper has a dotted line square grid, probably on ivory stock.
It seems slightly more yellow than standard staples printer paper, but MUCH less yellow than Midori MD cream paper.
Writing on the page...well, how do I describe it. The paper feels uncoated. It is textured. It felt like I was writing on regular printer paper, but without the ink bleeding/feathering. As soon as my nib hit the page it felt like it would feather and bleed, but it didn't.
I don't think there was much (or any?) feathering, nor bleed-through. Whereas Rhodia paper hates me whenever I use flex nibs, this paper impressively handled it like a champion.
Backside of the page has ghosting, but feels less than 52gsm Tomoe River. It's still usable to me.
Overall I felt that my pen/inks probably wrote a bit dryer on this paper. I touched some of the Logical Prime paper in my order, and that stuff definitely feels smoother and coated to the finger, compared to Logical Air.
The paper does show shading and sheen, but probably less than Tomoe River. I think the dry time is faster though! As mentioned previously, it felt like my inks wrote overall drier because of lack of coating/absorption, and that could lead to less sheen too. I'm not good at photographing sheen, but I do see a bit of it in the Lamy Turmaline and FPR Royal Flush Blue.
