KOKUYOCampus Refillable Notebook, A4 2x2 Slim Ring Binder Notebook with Customizable Title Page, 40 Sheets Capacity. Suitable for 30 Holes Loose Leaf Paper, Light Blue (RU-NP174LB)

I am left handed and have a hard time with notebooks. My hand will often lay across the spiral binding and start to hurt after a bit. I have the full size of these notebooks I use at work and love it. This size is perfect to keep in my purse as a diary. The paper is so smooth, and even works well with fountain pen ink. Shimmers and sheens are very visible, but it's not quite Tomoe River. Refills are an unbeatable price, and I love how thin the actual binder is. I can fold the cover over if needed. Individual papers can be removed and sorted into other folders for record keeping.One of my favorite writing setups at a really fantastic price.

I like how lightweight it is and that it’s basically a notebook plus binder combined you can change pages and remove pages. It’s really convenient for me as a student. The Look of it makes it more appealing to use as well as how slim it is helps with the overall weight when it comes to putting in a backpack. 100% worth the purchase for me! I wish there was a purple version.

A nice way to keep a limited amount of paper neat for use. Quick and easy to add or remove pages.

I like how you can rearrange the pages. I also like how it’s thin and slim.

I loved this product so much I bought another one for B5. Unfortunately, this one I got had warping/damage on the bottom rings and unable to be used properly.

The media could not be loaded. Since it’s slim it doesn’t take up space in my bag. Adding and removing pages is super easy and quiet unlike a binder which is good for when I’m in class or library.

The media could not be loaded. Smooth with no tooth. Paper smelled like sulphur. Overall though pretty good for organizing.

love Kokuyo products, this binder handles fewer sheets and would be great for reducing bulk in your bag. Fits Kokuyo Campus binder paper and other Japanese standard binder paper -- my personal preference is the Kokuyo Campus Sarasara for smooth writing.
