Although this seems like a simple cover, rest assured, as a product from Midori it is well-made and very nice. The flaps are stitched - not glued or taped.
The material itself is very stout - a thick, tear-resistant paper, not cardboard, that will develop a nice patina over time. Use it enough and it will take on a crumpled, worn-out, wabi-sabi appearance.
It comes in two sizes - A6 and A5 - and fits the Midori MD notebooks like a glove. It will also fit standard-size A6 and A5 notebooks not more than 12mm thick, with trimmed paper covers. Please note: it will NOT fit the Seven Seas A5 notebooks, as those are 15mm thick.
Notebook not included.
Made in Japan.
