For the last month I’ve been using a B5 Kokuyo Campus 2×2 ring binder and it’s turned out to be a perfect longform writing companion for me. The sheets are large enough to freewrite my Morning Pages into, and the flat writing experience is stellar; it lays flat! The absence of the wrings make it easy to reach the inside margins of the page.
Tools used in this spread include my Pilot Explorer medium nib pen filled with Noodler’s Brown, the sheets are Kokuyo Campus Sarasara, and the B5 variant of the 2×2 binder. I should consider getting one of these in A4 and I am already using the A5 version as my work notebook. I already own the similar A5 smart ring binder and it’s kinda gathering dust at the moment. Nooder’s Brown is an interesting ink. Upon a fresh fill of a pen it tends to write tan but as the ink gets darker as it works its way into the feed.

Note that the harsh lighting of these images are due to the LED bulb above my desk.
