Kokuyo Campus Smart Ring Binder, B5 Pink Refillable Binder Notebook 26 Holes with 10 Extra Loose-Leaf Paper, Up to 60 Filler Papers for Work & Study, Japan Import (RU-SP706P)

This B5 binder is very lightweight and slim, and it opens completely flat with a 360° fold, making it comfortable for taking notes or small projects. It comes with only 10 sheets, so you’ll need to purchase B5 refill paper with 26 holes if you plan to use it more.I also really like the variety of colors available and the cover material, which feels sturdy and made of good-quality plastic. Just be careful not to overload it, going over about 60 pages may cause the rings to open. The rings are a bit delicate, so they need to be handled gently.The opening mechanism isn’t very intuitive or user-friendly at first, but it works well once you understand it. I definitely recommend reading the instructions. I’ve also included an English translation of the instructions in case it helps others.

I love these for school work. I'm an online university student, and I like to print lecture slides, lessons, and worksheets so I don't have to stare at a screen as much. Other than these refillable notebooks I've tried many things, including creating my own spiral notebooks with a coil binding machine. I have about 12 of these now and never use the binding machine anymore.Here's why I love these:> I don't like the bulk that typically comes from binders, especially standard/A4/letter size. I also prefer to save space and paper by writing front and back, which typical binders don't allow you to do unless you have it fully expanded—increasing the bulk factor. These negate that issue and add virtually no additional bulk beyond the paper added. Even if you aren't an online student, these are far better than lugging around a bunch of giant 3 ring binders everywhere around campus.> Compared to the coil binding machine, these are far easier to use for the following reasons:> The Kokuyo prepunched 26-hole B5 paper that can be purchased separately saves me from having to punch stacks upon stacks of paper like I have to do with the binding machine, and I don't need to worry about misaligning the holes or anything.> Using these, I don't have to fuss with pliers and wire cutters for trimming and bending wire coils.> The plastic covers on these are far more effective (and attractive!) than the card stock I would use with the binding machine.> The durability and refillable nature of these allows me to use their convenience again and again, making them WELL worth the price. When a semester is over I can take the pages out, store them for later reference, and reuse the binders for the next courses. I can also continue to easily add/remove pages throughout the course. With the machine, once it's bound it's done.**I do recommend the 60 sheet capacity options for these binders as opposed to the lower (I think it's 25 sheet?) capacity options, as the lower capacity rings have a tendency to open on their own.

Paper is so smooth and nice to write on. A little but complicated to open for the first time but once you get the hang of it its great

Omg I love this notebook. It is the best and is definitely good for taking notes. I love that o am able to move around my papers. The cover is nice, have not gotten any tears. The paper is super thick and good for taking notes. Holds more paper then recommended.

My daughter loves this Kokuyo Campus Smart Ring Binder and is excited to use it for school. The B5 size is convenient for carrying around, and the refillable design makes it easy to add, remove, and organize pages as needed. The 26-hole system works well with compatible Kokuyo paper, and the extra loops are a nice feature for keeping everything organized.The clear design gives it a clean, modern look, and the binder feels lightweight without being bulky, making it great for school use. The rings open and close smoothly, and the overall construction feels durable enough for everyday handling. The refillable feature also makes it a better long-term option compared to disposable notebooks. The paper works well with different writing tools, and the pages have good bleed resistance with minimal ink showing through, helping keep notes neat and readable on both sides.Overall, this is a great choice for students who like to keep their notes organized and customize their school supplies. The quality, reusable design, and organization features make it a good value for the money, especially for students who use notebooks regularly.

Pros:-Light, slim, and very portable, easy to carry in a bag or backpack.-Refillable: you can add or rearrange pages thanks to 26-ring binding.-Comes with 10 sheets of loose-leaf refill paper, but you can replace or expand with more.-Cover folds back and the binder lies fairly flat, handy for writing or sketching while on the go.-Ideal B5 size: spacious enough for notes or journaling, yet more compact than letter-size binders.Cons:-Capacity is limited since it holds only a modest number of pages (so not great for heavy use or long-term large notebooks).The ring mechanism can feel a bit fiddly or delicate when adding/removing pages.-If you need to include full-size U.S. letter papers or non-B5 inserts, compatibility can be tricky (you’ll need properly punched B5 paper).- You may need to buy refill paper separately if you want to maintain the quality.Overall:The Kokuyo Campus Smart Ring Binder B5 s a smart, minimalist binder-notebook for note-taking, journaling, planning, or sketching, especially if you like flexibility and portability. It’s best for lighter, everyday use rather than heavy note-taking or large projects.

I’ve been using different versions of this Kokuyo Campus Smart Ring Binder for about 4 years now, and it has stayed a constant in my daily routine—first as a senior manager and later as a director.What makes this binder special for me is how clean, flexible, and practical it is. I deal with multiple topics at the same time—projects, people development, interview notes, career discussions—and being able to reorganize, add, or split sections easily is a huge advantage over traditional notebooks. It keeps my thinking structured without feeling rigid.The writing experience is also excellent. The paper feels smooth and soft, which sounds like a small thing but really matters when you’re taking notes all day. I use it regularly in meetings, interviews, and one-on-one conversations, and it always feels professional and intentional.Interestingly, I’ve even expanded its use beyond work. As a guitar player, I now use it to take quick notes while learning new songs—chord ideas, structure, small variations—because it’s just as easy to reorganize music notes as it is work topics.If I had one small concern, it’s that the plastic rings require a bit of gentle handling. They’ve never broken on me, but they don’t feel indestructible, so I’m slightly more careful when opening or rearranging pages.Overall, this is one of those products that quietly becomes part of your daily life. If you like staying organized, thinking on paper, and adapting your notes over time, this system is hard to beat.

the binder is very very very hard to get it open. I really want to like this because I heard so many good reviews and its concept is also very appealing. However, for the life of me, I don't know why it is so hard for me to open. It says to push down, but the binder ring itself is entirely plastic, and it would curve out in the middle when I apply force downward from the top. Probably 1 out of 10 times it will open. I still have not yet mastered it. Also since I took off the label and everything, I cannot return it. I have watched videos trying to learn the "proper way" of opening the binder, but it didn't look any different from how I am doing.

I LOVE these binders , they are excellent for work notes, light weight and excellent quality. The paper is smooth and nice to write on. You will not be disappointed

Should have this long time ago. It's so convenient you can open the note book and insert or remove pages. I notice there are complain about it only have 10 sheet of paper in the notebook, but you were suppose to buy the refills.

I think I have bought every one of these I can find on here at this point. I love them. They are like a binder but smaller and more rings. You can also get variants different kinds of paper. They are delightful

家計簿に買いました。とても使いやすく、小型で色も良く、とても使いやすく気に入っています。開け方も親切に説明付きです。おすすめです。有難うございました☆

Es más práctico si solo quieres tomar los apuntes del día y no llevar tanta carga en tu mochila o en tus manos
