Three I've used in this cover are Muji B5, Apica 6A10 and Kokoyu Campus B5 notebooks.All fit well. Personally I like the Kokuyo notebooks the best.

pelahale has a video showing the Systemic Semi B5 with examples of a smaller Rhodia (maybe A5 No. 16), Mnemosyne, and Apica CD notebooks in it. In the video he calls it "B5" size but as far as I know the Systemic itself is described as Semi B5.




Semi B5 is 179mm x 252mm

ISO B5 is 176mm x 250mm


I bought one of these for someone for Christmas last year and don't have it so I can't measure its outside dimensions. You'll see in the video that the various pockets and sleeves in the Kokuyo Systemic offer a lot of possibilities for slightly smaller notebooks to fit. Obviously Campus Semi B5 notebooks from Kokuyo fit. Also the Apica CD25 spiral bound.


Since ISO B5 is smaller than Semi B5 (by just a few mm in each direction) you can be confident that ISO B5 would fit inside it without a problem.


Paper labeled as Japanese B5 is a little bit larger but I think also fits.

JIS B5 is 182mm x 257mm

This is the Apica C.D. B5 notebook size. This clearly fits in pelahale's Systemic notebook as you can see in the video.


So the upshot is that JIS B5, Semi B5, and ISO B5 notebooks will all fit in this notebook case.

Yes, I use the Apica 6A-10 with the Systemic Semi-B5, and I love the combination. The Apica 6A-10 has 100 sheets of paper, so it's good for big projects--but being tossed into my briefcase and hauled out twice a day was taking its toll on the Apica's cardboard cover. Not only does the Systemic cover protect the Apica, but it permits the Apica to open flat. I keep a piece of blotting paper in one of the front inside pockets.

      Even so, you'd end up with a fragmented list, and it becomes an O(N²) process for each prospective requestor to check what is available: effectively recreate the list of currently active servers (without any reliable up-to-date info upfront about the inks and number of samples on offer in the thread) from the sequential list of posts, which may be spread over two or even more pages, and then query each server independently to check what is currently on offer.   It comes down to not hav

      If one wanted to do this, one could just use the "About Me" field which appears to be unlimited in size.  And if a bunch of people wanted to cooperate, the Member Title field (or signature) could be used to this end - "Ink Giver" (or some such) could be used by those with inks to give...  No software edits required.

      I suppose the update issue could be mitigated.  One would post a link in signature, to the particular part of your profile where you list the inks that you're willing to post samples to others, gratis.  But looking at profiles, I suspect that would require an edit to the board's software, potentially a nontrivial task.

      I read your idea as getting willing givers to publicly register as members of a set of heterogenous servers, in a system in which a client would explicitly select an available server from a list, to which he/she will then send a request privately and asynchronously. Request handling in the system is unmanaged, and individual requests are handled by the targeted servers completely independently on each other. I think the model is fine, although there are some operational concerns you may want to

      First thought on the method/system of ink sharing: Think the best way, to begin with, is to follow the way of the US thread: offer up a (small) list of inks you are willing to PIF, to whoever expresses interest. Write clearly in the "mission statement" how it works, with a tiny "quid pro quo" that even a struggling student can comply with, i.e. post your opinion and a writing sample, with option of a full review if desired.   So yours truly might say: "I'm offering up samples of D
