I purchased these several times and then completely happy especially with the quick delivery. ### ⭐⭐⭐⭐ Machine does a fine job punching *by K***. on September 13, 2020* The machine does a great job punching - 20 page limit could be a little overstated. I use 20 lb paper and found 15 pages was easier - you can do 20 pages, but it seems to put more stress on the handle that i am comfortable with. The issue i have is with coils - they are easy enough to feed through, but after trimming - they are not secure and tend to wonder out of the punched holes. There was no documentation in the package so it could be an operator problem. Will try to find the procedure on line. --- ## 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.com.sa/products/5637913-8mm-5-16-in-spiral-binding-coils-for-reports-presentations](https://www.desertcart.com.sa/products/5637913-8mm-5-16-in-spiral-binding-coils-for-reports-presentations) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-10-28*
