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. ## Frequently Bought Together - KOKUYO Campus Smart Ring Binder Notebooks, A5, 25 Sheets Capacity, 20 Rings, Clear, Japan Import (RU-SP130T) - Kokuyo Campus Loose Leaf Paper - Sarasara - A5 - Dotted 6 mm Rule - 20 Holes - 100 Sheets - Kokuyo Campus Loose Leaf Paper for Binders, Sarasara Smooth Writing, A5, 5mm Grid Ruled, 20 Holes, 60 Sheets, pH Neutral, Bleed Resistant, 75gsm, Japan Import (NO-807S-5) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/31962584-smart-ring-binder-a5-clear-binder-notebook-up-to-25](https://www.desertcart.jp/products/31962584-smart-ring-binder-a5-clear-binder-notebook-up-to-25) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-14*
