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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Must-Have for Precision Layout Work *by H***Ć on April 3, 2026* This is a must-have if you do any kind of woodworking or layout work.

It feels sturdy, well-made, and has a great quality to it. You can definitely tell it’s built to last, and I’m confident it will serve me well for a long time. Very happy with my purchase! ### ⭐⭐⭐⭐ Not what I expected. *by S***. on April 13, 2026* I never write reviews but for this I will make an exception. It is not at all what I expected. It is very heavy. The one on the right is 1.5oz, the Mr. Pen is 7.5oz. It's massive in comparison. You could stab the neighbor's mastiff with it. If you are looking for a compass made of German steel with precision you will be disappointed. This is not the one, however it is not without its charm. After the better part of an hour of sanding, filing and a few trips to the oscillating spindle sander it is smoother and the rough edges are knocked off. The head joint pin is rock solid....matter of fact it's a bit too tight. Little bit of oil and some back in forth and it's better. The wing nut threads are a bit sandy feeling but passable. It will probably smooth out over time. It appears to be made by hand in a machine shop. No stamped parts except maybe the wing, but it's well made if a bit crude. If I were to place this beside my 9 1/2 Stanley block plane(which I like better than my Veritas) you would have a hard time discerning that they were not built in the same era. There is no Made In China stamp on it. It takes a number two pencil and holds it fast and draws circles very well. The design is simple, solid and effective. It's what a good tool should be. And it's not too spendy. The only knock I have is the rough edges. I'd like to see a 2.0 version with a little more finesse. ## 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.com.au/products/214776036-mr-pen-professional-compass-for-woodworking-compass-with-wing](https://www.desertcart.com.au/products/214776036-mr-pen-professional-compass-for-woodworking-compass-with-wing) --- *Product available on Desertcart Australia* *Store origin: AU* *Last updated: 2026-09-25*
