## Description

desertcart.com : Kokuyo Campus Smart Ring Binder, A5 Light Blue Refillable Binder Notebook 20 Holes with 10 Extra Loose-Leaf Paper, Up to 25 Filler Papers for Work & Study, Japan Import (RU-SP130LB) : Round Ring Binders : Office Products

Review: I love Kokuyo - It opens fairly easily now that I know how. If I read Japanese I'd have known how not to open it the first time, but no harm done. Translation via Google Lens is really helpful for Kokuyo products. I like being able to fold the covers around back to back for writing to give some stiffness, especially with their small capacity. I also have a Kokuyo 2x2 slim binder. I keep one at home and carry one in my bag and transfer sheets between them as needed. Great paper for fountain pens at a good price, so I bought plenty of filler paper. I like having a spiral notebook I can add and remove pages from.
Review: It's fine - It's fine. You can't really flip the cover around to the back.--it doesn't lay flat. I'd suggest Kokuyo paper and a Muji cover/binder.

## Questions & Answers

**Q: How many sheets will fit in this notebook?**
A: Short answer: 40 Sheets max. Long answer: It depends on weight of paper. A5 20 Ring filler paper is not that easy to find, but some different weights (= paper thickness) are available from Kokuyo and Maruman. Also too much paper can cause sheets to catch while turning and notebook to not lay as flat when folded back.  I use this for a simple portable notebook and like to keep filled with about 20 sheets of "original" Kokuyo 807BT paper.

**Q: How many pages are in each notebook?**
A: 10 sheets. It's recommended you purchase the notebook refills if you're planning to use the notebook frequently!

**Q: Does it come with some paper?**
A: Yes, it came with 30 sheets (60 pgs) of paper.

**Q: Are these blank pages or lined?**
A: We ordered the lined paper for the A5.  We also have since ordered the B5 and ordered graph paper for it, as well as the lined.

### ⭐⭐⭐⭐⭐ the only notebook you'll ever own
*by O***8 on January 11, 2020*

I saw this in a Japanese based stationary shop and decided to give this a try. I have the larger size (B6?) which is a close size to a composition book ~ if I was in college I would definitely go with the larger size. This size A5 is the size of a 8.5x11 folded in 1/2. This notebook is amazing! I can carry as little or as many pages of paper and I can move it all around (which allows me to group different subjects together ... home remodeling, parent's health care, work and/or children's school related things. You'll only need one notebook since you can always add and remove paper once you purchase the notebook. I don't know why I wasn't aware about this in college. This would be a life changer for me then!!
