Kokuyo Campus Smart Ring Binder, B5 Blue Green Refillable Binder Notebook 26 Holes with 10 Extra Loose-Leaf Paper, Up to 60 Filler Papers for Work & Study, Japan Import (RU-SP706BG)

It’s so pricey for nothing honestly it breaks my heart someone can pay this much for a notebook binder

I love this binder. It took a little getting used to how it opens the clips, but once you figure it out it's super easy. The outer color is super cute, and I love that it holds quite a lot. I've been using it for my Japanese studies, and even if you didn't get this for study purpouses it would be great for other uses; such as paper retention, note taking, doodling, organizing, and so forth. It functions for well and I highly recommend it, it has kept all my notes safe. The price is worth it!

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

Smooth paper, easy to remove. I use this every school year

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.

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.
