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

**Q: is this the right size for regular notebook paper in North America?**
A: No, it will not fit letter size paper or filler paper. You need to buy A5 paper with 26 holes for this binder.
