KOKUYOCampus Smart Ring Binders 3 Pack, B5 Notebook Binder +100 Sheet Refiller Paper, 25 Sheet Capacity, 26 Rings, Light Color, Perfect for Work, Study & Journal, Japan Import

I purchased these for my son and took one for myself. I love these notebooks I love the fact that I can add and remove paper. These are spiral notebooks with the benefit of opening up like a binder. The paper is nicer than regular notebook paper, very smooth to the touch. I love writing on this paper. The drawback is that you only get 25 pages in one of these notebooks, and they might only hold as much as 50 sheets. The replacement packs can get expensive as well. They are not as wide as a regular notebook. They are a B5 sized paper. Even though there are some pretty expensive drawbacks I do still love the notebooks and I am happy with the purchase.

Slim extangable paper binder/notebook.Works well, not flimsy saves so much money from buying notebooks over and over again from them falling apart.

Even thought you can't do the folding thing, it's still a pretty good notebook. I love being able to fill it with paper as I can customize the cover to be my own. The paper is nice and smooth, nice to rest my hand on as a right handed. I will say that if you are left handed it might not be too comfortable. It's small but good for hand written notes. I will definitely keep these for a long while.

they are really nice and efficient. i use these for school and have been for a while. they get scratched pretty easily and often unclip from the paper and covers, leaving the spiral spine part floating in my bag… but theyre so useful. 😭😭

Kokuyo Campus Smart Ring Binders 3 Pack, B5 Light Colors Binder Notebooks, Up to 25 Sheets 20 Holes Slim Binder Folder and 100 Campus Sarasara Loose-leaf Paper for Work, Study & Journal, Japan Import ($21.03)Interesting binders. Special request from a relative for back-to-school. They are very happy with the look and usefulness of these binders/notebook. These are thin, so would be ideal for school subjects that does not require a lot of paper/writing. I do like that they can be used over and over.

these are my favorite binders. they’re very light and thin so i can carry a bunch at once. paper quality is also very good

The best binder I have ever had. The quality of paper is great.

Love the fact you can move the pages around with the ring binder. Hate the feel of the paper. The ring binder also isn't compatible with other types of paper so you have to stick with theirs unless you try to put the same shape holes in another type of paper to match this notebook. It's indeed slim especially because you can take paper out and in. The binder is fine and easy to use but occasionally opens itself in my backpack. Also the binder is thicker than the notebook so you can't get it flat unless you lay the notebook both sides entirely face down/up. That makes it difficult to write on as well. That and the awful paper to write on are the main reasons I wouldn't buy this again. It seems cute and great, but unless you value slimness over anything else in the world, just get a cheap notebook it's fine.
