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. ## Frequently Bought Together - KOKUYO Campus Smart Ring Binder Notebooks, A5, 20 Capacity, 26 Rings, Light Blue, Perfect for Class or Work, Japan Import (RU-SP130LB). - Kokuyo Campus Loose Leaf Paper - Sarasara - A5 - Dotted 6 mm Rule - 20 Holes - 100 Sheets - KOKUYO Campus Smart Ring Binder Notebooks, A5, 25 Sheets Capacity, 20 Rings, Clear, Japan Import (RU-SP130T) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/589662869-campus-smart-ring-binder-a5-20-rings-light-blue-office](https://www.desertcart.kr/products/589662869-campus-smart-ring-binder-a5-20-rings-light-blue-office) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-07-05*
