Kokuyo Smart Ring Binder, B5 Light Blue Binder Notebook, Up to 60 Sheets

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.

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.

I love the style and color! It holds all my paper work

I love my kokuyo. I use it to keep my work information separate. I carry a lot of documents around and my bag is always heavy. This binder keeps all my information in one place and is very very thin. like that I can add pages if I need to but is thin and not heavy. Love this brand. Highly 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.

Love the refillable notebook, it’s small enough and very durable

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.

A nice notebook, but opening and closing the rings is a challenge. The instructions are in Japanese, and the illustrations designed to instruct the user are not very helpful. Decent for the price. Hopefully I will enjoy it more as I use it.

Buena calidad (para abrir se tiene que precionar hacia abajo para abrirlo y ya con el seguro quitado)

Perfect my kid is happy about it

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☆

色が気に入ったので買った。バインダの開閉は少しコツが要るように感じる。背中の出っ張りが少し大きい。それ以外は、つかいやすい普通のルーズリーフ。ピンクも買い足した。

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
