## Description

desertcart.com : Kokuyo Campus Smart Ring Binder, B5 Light Blue Refillable Binder Notebook 26 Holes with 10 Extra Loose-Leaf Paper, Up to 60 Filler Papers for Work & Study, Japan Import (RU-SP706LB) : Office Products

Review: Slim, Flexible, and Great for Students - 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.
Review: Lightweight and practical B5 binder - 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.
