We now have a compass that works well and that one must have been a one off one that has a problem. My son loves it and the feature where you push both bottoms to expand it quickly is super useful when he is doing his geometry homework. That way, he doesn’t have waste time using the small dial to expand the leg or reduce the size. β€”β€”β€”β€”- (Old review) I was excited to get this for my son for his Geometry class. So was he. All are great such as refills, extra screws, the little metal plate as a screw driver to tighten the screw for the leg that bends, additional leg to draw a big circle (although this isn't necessary for his class), but one slight oversight which is annoying to use is the screw that tightens the legs from bending. The screw head is so shallow, I cannot tighten it before threading the screw. Needless to say that I cannot tighten it. So, when my son uses it, it kept bending when he's putting his point down on the paper firmly so that the compass won't slip off. I told him to grab the bottom part of the leg while he is pushing down on it. Contemplating on returning it and see if we can get the proper one to tighten the legs. But the inconvenience of it... sigh... If they could just replace the screw (if that screw can be replaced), that would be perfect. All other features function fine and would have been a great compass with 5 stars. Review: I LOVE this compass! - I had previously ordered a different compass here on desertcart, and it was absolutely terrible. Thumb screws that were too tiny and were plastic, so if you tighten them just a little bit too much they broke. No well-defined channels for the lead or point to sit in, so centering them was impossible, making the setup process a total exercise in frustration. I went back to desertcart to find something better, and thought I'd give Mr. Pen a try. Well, the mail just got here about an hour ago, and there it was - my new Mr. Pen compass! The clouds parted and the sun shone down! I love you Mr. Pen! Please don't tell my husband! I couldn't be happier with this compass! Solid construction - it's got some weight to it, but not too much. Clearly defined channels for the lead and the metal point - they just sit right in there and are ready to go. Thumb screws that are the right size to not make you feel like your hands are ridiculously large, and the button release levers for adjustments are magical - no turning the wheel for hours to change from a tiny circle to a large one! The extension arm has a widely adjustable pencil holder that you can fit pretty much any writing implement in - even a Sharpie. And to top it all off - a mustache decal! I couldn't be happier with my new Mr. Pen compass!! Thanks for making my day, Mr. Pen :-) ## Features - Professional Compass With Universal Adapter, Extension Beam For Math, Geometry, Art, Drafting And Drawing, Creates Circles Up To 18 Inches In Diameter - Precision Geometry Compass With Spring Bow Head And Center Wheel Accompanied Quick Setting Adjustment With Push Button - Mechanism Prevents Unintentional Leg Movements - Premium Quality, Life-Time Satisfaction Guaranteed 10 Extra Lead, Spare Needle And Screws And Screw Driver Packaged In A Clear, Reusable Pouch.

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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great features, solid and awesome customer service *by E***A on July 30, 2019* Update: I contacted the seller and his response was super fast and sorted out the problem right away.

Thanks for making my day, Mr. Pen :-) ### ⭐⭐⭐⭐ Solid, but not satisfying. *by R***Y on January 13, 2021* For the most part, the compass is reasonably well built. I was excited to get it, but after using it, am not quite as thrilled. 1) the angle adjustments mid-leg are not as stiff as I'd like. I'd probably have chosen a solid leg instead. 2) The universal pencil holder is plastic and also not quite as stiff. Screws on it are plastic, leaving me cautious about damaging them. 3) It includes a four extra knobs... and two needle points, more than needed, but no extra screws should any of those be lost. Maybe balance those extra pieces out to just two extra knobs and two extra pins. 4) The extension arm was difficult to put on, due to tolerances being slightly off, but once on was quite solid. 5) Not quite as clear in the video is that the end point can be slid anywhere along its length (+) but the end piece is also plastic (-) 6) I do like the adustment knob. But, while my last compass didn't have one, the actual hinge was much stiffer. See photo. I believe this is largely due to it having a bigger screw creating friction at the joint. With this one, the hing itself has two smaller screws and is looser. The threads on the wheel still give enough play that it is actually less precise feeling - though that may be partly because it is almost twice the size. The arc drawn on the paper shows this 1-2mm of play that can occur. 7) The last bit - and this is where I have a hard time articulating, but caries the most weight: This compass is not as easy to use as my previous one (which broke unfotunately and I can't find the tip). I'm not sure if is because the points are not as sharp, if it is just bigger, and heavier, but it tended to lose hold on the pivot more easily, which was frustrating. 8) A better case could be nice. But not a deal breaker. My conclusion - comparing this to my old compass is not apples to apples. The old was cheap, but felt more precise, probably largely because it was only half the size, with solid legs, and solid connection to the pencil holder. For this model, it is more flexible, but the additional features come at a cost of precision. Still pretty good, but if you want precision, you need something that is either machined with very high tolerances and better engineered, or a simple, solid compass. Price aside, I'd give it 3 starts. but it was cheap, so 4 stars. I don't have the heart to rate it at 3 givent the price. ## 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? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/110451749-mr-pen-professional-metal-compass-set-7-pcs](https://www.desertcart.vn/products/110451749-mr-pen-professional-metal-compass-set-7-pcs) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-09-06*
