The description says 18" while the video says 24"** A: With the "extender leg" attached I am able to open the compass to a diameter of 11.5". I don't see how you could expand it to 18" or 24". **Q: Can you use this with other drawing utensils like markers?** A: Yes you can use markers and pens and pencils. Built in there is a lead, but there's an attachment that lets you use any kind of writing pen/marker/pencil that is up to 1/2 in diameter. **Q: What is the diameter of the lead? I need more than the standard black lead. Most compass's are 2mm>** A: This is also 2mm. Make one, there's plenty of cool compass plans available online. That's what I did for my trammel points (beam compass) **Q: Does the small compass use the same 2 mm replacement leads?** A: Yes ## Frequently Bought Together - Mr. Pen- Professional Metal Compass with Wheel and Lock for Geometry, Compass Geometry Tool, Drawing Compass, Drafting Compass, Math Compass, Geometry Compass, Compass Drawing Tool, Compass Math - DIYSELF 1 Pcs Craft Hobby Knife Exacto Knife with 11 Pcs Stainless Steel Blade Kit, 1pcs Steel 15CM Ruler for Art, Scrapbooking, Stencil (Purple) - Calligraphy Pen Set --- ## 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.br/products/110451749-mr-pen-professional-metal-compass-set-7-pcs-precision-drafting](https://www.desertcart.com.br/products/110451749-mr-pen-professional-metal-compass-set-7-pcs-precision-drafting) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-07-23*
