Review: Cute and versatile - So I didn’t know but mixed layout A5 spiral notebooks are super rare and the one I bought years ago is about to be full so after scouring the internet I came across these binder notebooks because they’re modular so now I can have grid paper in one section, blank in another and dotted lined paper too! I almost didn’t purchase because I saw that it holds like 25~ pages but you can definitely comfortably add way more. I added my own stickers to personalize the binder covers but I’m so excited to use this notebook!! The pages feel so premium too!! I love it :•)

## 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.
