I suppose you could tape the marker to it, but it won't fit in the holder. **Q: How do you get it to open. I received mine in the mail today and I can’t get it to spread apart** A: All you have to do is to simply spread it apart as needed. You may have to use a little pressure. One thing that could cause trouble is the little black locking nut on the top. Make sure it is loose first Just turn it counter-clockwise to loosen it. To fit a regular number 2 pencil in the holder, you may have to sand it down a little. **Q: Great Compass , but we’re missing the two set screws 😥** A: The carpenter's 12" compass I received lacked the locking and pencil retention screws necessary for its use. I e-mailed the Mr. Pen folks to request the screws early that evening. They responded via e-mail around three the next morning apologizing for the problem and stating that if I'd send them my Amazon order number they would be happy to send me a new compass. I did so and received notification that my order had shipped that same day. Two days later I received my new compass. No hassle and prompt, cheerful customer service make this a great outfit to do business with. And yes, the product was of great quality. ## Frequently Bought Together - Mr. Pen- Professional Large Compass for Woodworking, 12 Inch Compass with Wing, Compass for Geometry, Compass Drawing Tool, Woodworking Compass, Pencil Compass for Carpenter, Drafting, Drawing Compass - Mr. Pen- Professional Compass for Geometry, Extra Lead, Metal Compass, Compass, Compass Drawing Tool, Drawing Compass, Drafting Compass, Compass for Students, Compass for Woodworking, Compass Geometry --- ## 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.us/products/500580908-mr-pen-professional-compass-for-woodworking-8-inch-compass-wing](https://www.desertcart.us/products/500580908-mr-pen-professional-compass-for-woodworking-8-inch-compass-wing) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-22*
