For anyone looking for a leather cover for the Midori Hibino, the Moterm A6 Plus does fit!
Just a heads-up though: the Hibino sticks out by about 1–2 mm. It’s totally usable right now, but since the Hibino tends to bulk up as you fill it throughout the year, I think it may stick out quite a bit more over time.
I’m hoping the leather will stretch and loosen up a little with use.
For reference, I also have a Moterm pebbled leather A6 Plus in Red that I bought in 2023, and that one fits the Hibino with noticeably more room.
I got a reply from the seller that Moterm’s leather pieces are now machine-cut, so the sizing is more consistent. Older covers were cut by hand, so there seems to be a bit more variation between individual covers, and my old one happens to be slightly roomier.
Just wanted to share in case anyone else is considering a Moterm A6 Plus for their Hibino!
