Cute and versatile
So I didn’t know but mixed layout A5 spiral notebooks are super rare and the one I bought years ago is about to be full so after scouring the internet I came across these binder notebooks because they’re modular so now I can have grid paper in one section, blank in another and dotted lined paper too! I almost didn’t purchase because I saw that it holds like 25~ pages but you can definitely comfortably add way more.I added my own stickers to personalize the binder covers but I’m so excited to use this notebook!! The pages feel so premium too!! I love it :•)

It’s great
This is the best binder notebook I’ve used. The rings are soft so they don’t bend into stuff. The feel is very premium and it lays flats.

I do like the campus paper it comes with
This notebook is smaller than typical copy paper.The notebook itself comes with 10 sheets of paper. If you want more, I highly suggest Muji's paper. They sell about 100 sheets of graph paper for this notebook for 2 bucks, which is cheaper compared to the campus paper on amazon. I do like the campus paper it comes with, but personally it is too much money.The notebook cover is sturdy and a medium-thick plastic.The cover is see through, so keep that in mind.The listed paper capacity is 25 sheets.I believe it is listed as so, because if you were to fold it like a spiral notebook to write on just one page, all the rings are closed.I have been able to fit 40 sheets of paper comfortably, but you cannot fold it over to write on just one page. The rings will spread apart.I noticed that after 50 sheets of paper, the rings no longer close fully, so paper has a chance of falling out.I personally love this notebook. I like to use one notebook per class, and typically I do not fully use a notebook. This allows me to use it as a regular notebook, but when I am done I can replace the pages.I also scan all of my notes into my computer for safekeeping (and so I don't keep notebooks around for years on end), and having the paper come out with no fringe is a bonus.The other added bonus is that I can take out a sheet of paper and write on it, if writing in the notebook is hard. Rearranging pages is also lovely, and very useful for notes and inserting diagrams.I have not personally tried to hole punch things to put in the binder, but I have heard about people using Carl's 26 hole puncher with great success. It is possible if you would want to create your own paper for the notebook.The only thing I wish I could change is how many pages it could hold. It would be lovely if it could hold around 70 to 100 pages, like most US standard notebooks.

Amazing Technology! Wonderful Notebook!
I have been going to school for nearly 15 years now, and have been writing on traditional Staples notebooks for my whole life! Though they are only 10 cents per subject notebook, I always faced the problem of wanting to move my pages around into a custom configuration.This year, I have sat next to a foreign exchange student from China who has many of these notebooks! The paticular notebook that he has, is the multi-subject one with sections in it.This technology is great. THIS NOTEBOOK COMES WITH ONLY 10 PAGES. You have to order your own B5 paper which is sold in 100/packs on Amazon too. The paper is smaller than traditional notebooks, and is much more durable. The downside is that you are not able to tear out pieces of paper cleanly (without the bindings).This notebook is nice and portable and fits in a lap-top case!Defiantly would recommend this to anyone on the go, for note taking and someone who does not want to take a large notebook with them. This product you can choose how much paper you carry.The only downside I have seen/had with this product so far is that the binding that hold the notebook together does not feel too strong, I feel like if I bend it a little too much that it could break. But it is defiantly safe in a crowded backpack with other accessories!EXPLANATION:For those who have not seen this product in person, the images do not do a good job of explaining its purpose. This not book is a mix of a traditional "american" 3 ring binder that is able to open up, and a regular notebook. All 26 of the notebook bindings open up, and allow you to move around the notebook pages freely. So you are able to keep your note together, or your homework together. The paper is "refillable" so this is a product that will last.

Flexibility of a binder, footprint of a notebook
I have found this to be very helpful in my studies. I am a medical student, and I have found it is helpful to use paper to help cement tricky concepts vs digital note taking. I also use this for practice problems. I have appreciated the ability to remove/rearrange pages like a binder, while having the slim profile of a notebook. The closure took a little getting used to, and it popped open once when I accidentally put it in my bag upside down. Be cognizant of how you handle it and you should have no problems. So far it has held up to repeated opening/closing, and seems durable enough, but I wouldn't recommend storing it in a bag where it is going to get crushed/jostled by other items. I have found the size is suitable for portable use, fitting in not just backpacks, but also totes or large purses.Overall, I have enjoyed the experience of using this with paper I ordered from the same company (item number NO-836BT). Combined, they provide a lovely writing experience.

color is off. mechanism (spring) is flimsy
I have been using Kokuyo products for years, but this mechanism is not as great. maybe i got a faulty part. it's quite flimsy and opens up ever so slightly with the tension of paper added to it. i tried not adding too much but it's still opening. i tried adjusting and closing it by pushing with my fingers but it still does not quite stay closed/ no "click". the color is more teal than blue. i purchased this color specifically as a darker alternative that conceals the contents enough, i don't feel it's quite as dark as i need but ok, wish it was about 30% darker or denser. the paper is as always smooth. the plastic itself is good thickness.

Fav notebook
I use this notebook because I don't like the bulky ones. I also love how the rings are flexible because as a left hand person they can get in the way when I write. Super cute and worth it!

perfect notebook.
this notebook/binder hybrid was exactly as described and is just what i needed. traditional spiral notebooks don't work for me as i'm left handed (using them is generally uncomfortable). this one is perfect as i can take notes on the looseleaf sheets (10 were provided with the notebook and you can easily find packs of 100 on amazon) and then place them inside the binder. price was also fairly reasonable considering the quality and that a regular binder from staples is around 10$.

¡La portada es fantástica!
Es muy delgada y tiene un tacto muy agradable. El mecanismo de anillas es interesante y también muy práctico. Viene con unas 20 hojas incluidas.
