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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by 購***者 on 22 February 2026* こんなに軽くて薄いタイプのバインダーを探してました！A5なのでほぼ日カズン手帳の中身に使わせてもらいます！ ### ⭐⭐⭐⭐⭐ Review *by R***R on 6 August 2025* Excelente producto duradero y práctico ### ⭐⭐⭐⭐⭐ Review *by R***R on 10 May 2024* It's a delicate binder and should be handled with care, but I think it's worth it. It is incredibly slim, and after I figured out the ring mechanism, I never want to go back to metal binder rings. The only thing I haven't liked is that the cover is so flexible that you really have to use the notebook on a flat surface; however I took a few minutes to DIY a shitajiki insert to add stability and it's perfect. I'm going to order more in other colors to hold old notes and journal pages. ## 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? - 🛒 **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.at/products/261941806-campus-smart-ring-binder-a5-clear-refillable-binder-notebook-20](https://www.desertcart.at/products/261941806-campus-smart-ring-binder-a5-clear-refillable-binder-notebook-20) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-04-23*
