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 Geometry Set Metal Compass, 7 pcs, Geometry Precision Tool Set with Shatterproof Storage Box, Drafting Tools & Drafting Kits, Circle Drawing Tools for Engineers Students - Nicpro 6PCS Art Mechanical Pencil Set, 3PCS Metal Drafting Pencil 0.5 mm & 0.7 mm & 0.9 mm & 3PCS 2mm Graphite Lead Holder (2B HB 2H) For Writing, Sketching Drawing With Lead Refills Case - Architectural Scale Ruler, 12" Aluminum Architect Scale, Triangular Ruler for Blueprint, Triangle Drafting Metal Architecture --- ## 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.au/products/422898955-mr-pen-professional-geometry-set-metal-compass-7-pcs-geometry](https://www.desertcart.com.au/products/422898955-mr-pen-professional-geometry-set-metal-compass-7-pcs-geometry) --- *Product available on Desertcart Australia* *Store origin: AU* *Last updated: 2026-09-19*
