I love Kokuyo
It opens fairly easily now that I know how. If I read Japanese I'd have known how not to open it the first time, but no harm done. Translation via Google Lens is really helpful for Kokuyo products. I like being able to fold the covers around back to back for writing to give some stiffness, especially with their small capacity. I also have a Kokuyo 2x2 slim binder. I keep one at home and carry one in my bag and transfer sheets between them as needed. Great paper for fountain pens at a good price, so I bought plenty of filler paper. I like having a spiral notebook I can add and remove pages from.

It's fine
It's fine. You can't really flip the cover around to the back.--it doesn't lay flat. I'd suggest Kokuyo paper and a Muji cover/binder.

the only notebook you'll ever own
I saw this in a Japanese based stationary shop and decided to give this a try. I have the larger size (B6?) which is a close size to a composition book ~ if I was in college I would definitely go with the larger size. This size A5 is the size of a 8.5x11 folded in 1/2. This notebook is amazing! I can carry as little or as many pages of paper and I can move it all around (which allows me to group different subjects together ... home remodeling, parent's health care, work and/or children's school related things. You'll only need one notebook since you can always add and remove paper once you purchase the notebook. I don't know why I wasn't aware about this in college. This would be a life changer for me then!!

Holds 25 sheets, nothing more
The ring mechanism is nice and easy to use once you understand it, but it prevents you from folding this over so only one page is exposed. It also limits the amount of sheets you can have to around 25 total. Anything more than that and the rings start to get caught on the paper and it's hard to turn pages.

Broken.
It came in broken and scratched up, it feels like very cheap quality…. Amazon won’t let me return it so it feels like a waste of money. I reached out to the company’s customer service waiting for a response.
