## Description

Kokuyo Campus Smart Ring Binder, Up to 25 Sheets, A5, 20 Holes, Japan Import (RU-SP130T)

Review: So so - It came in perfect condition but the reason I wont give 5 stars to this product is just because it is not super sturdy I used it for about 2 years and the closing mechanism now is not functioning properly. You might say 2 years is a lot and you are absolutely right but comparing to the lifetime of a binder.. Regardless it was well loved while it lasted!
Review: Easy to use and really nice to write on! - Brilliant product. Really soft paper to write on, really smooth!

## 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.
