Note: Punching fewer sheets each time helps extend blade lifespan. ## Frequently Bought Together - TIANSE Binding Machine, 21-Holes, 450 Sheets, Comb Binding Machines with Starter Kit 100 PCS 3/8'' Comb Binding Spines, Comb Binder Machine Book Maker Perfect for Letter Size, A4, A5 or Smaller Sizes - Fellowes 52089 Binding Presentation Covers, 8mil, Letter, 100 Pack, Clear - Yunsailing 150 Pack Plastic Binding Combs Plastic Binder Comb Ring 19 Ring Binding Spines Letter Size Spiral coils for Notebook Calendar(1/4 5/16 3/8 1/2 5/8 3/4 in,Black) --- ## 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.pt/products/350490890-binding-machine-21-hole-450-sheet-comb-machine-with-starter](https://www.desertcart.pt/products/350490890-binding-machine-21-hole-450-sheet-comb-machine-with-starter) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-23*
