Also you can use them to mark measurements on paper, wood and...So you measure something with your divider then you can transfer it to other things, multiple times, without measuring again and again or leaving a mark with pencils or pens. **Q: does the divider have a screw adjustment?** A: The metal compasses do. The 6" plastic protractor with swing arm doesn't. **Q: How do you use the protractor with the swing arm? What's the added benefit over using a regular protractor?** A: Hello, Thank you fir your question. The swing arm really helps if you are trying to draw a curve with a certain angle. It can also help you to be more accurate when measuring an angle. **Q: How do i change the the lead on the compass? it does not seem to be removal. i might do it incorrectly. thank you.** A: There is a small knurled knob just above the lead. You have to loosen that knob; 'righty tighty, lefty loosey'. Or Counter clockwise to loosen. You find it a little bit of a challenge to grab the lead and pull it down, to adjust, or all the way out. It's graphite, which is slippery. Don't need to take the knob off, just loosen it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very happy *by H***T on 12 April 2024* Good quality ### ⭐ Mala calidad y tamaño *by R***B on 13 March 2019* Acabé por devolver el producto. No da la relación de precio-calidad ### ⭐⭐⭐⭐⭐ Perfect architecture kit! *by S***S on 14 April 2026* As an architecture student this is great to have. I no longer have to worry about what tools are needed as the kit has pretty much everything you need. I also liked that the cost was not too pricy. Along with it being light weight and a perfect size to fit in any backpack without taking up a bunch of space. Definitely will be buying again, and the hand written note and the sticker was really cute. ## Frequently Bought Together - Mr. Pen Geometry Set with 6 Inch Swing Arm Protractor, Divider, Set Squares, Ruler, Compasses and Protractor, 15 Piece Set - Zaviko Graph Paper Pad 8.5 x 11, 2 Pack, 4x4 Graph Ruled, Grid Paper Pad 8-1/2" x 11", Blueprint Quadrille Pad, Easy Tears Off, Grid Pad Notebook 8.5 x 11, White 70 GSM Graft Paper, 30 Sheets/Pad - Rena Chris Architectural Scale Ruler: 12" Imperial Aluminum Alloy Metal Architecture Measuring Tools, Engineering Drafting Construction Drawing Blueprints Triangular Architect Scaling Rulers 12 Inches --- ## 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.pt/products/257238365-mr-pen-15-pcs-compass-set-with-swing-arm-protractor](https://www.desertcart.pt/products/257238365-mr-pen-15-pcs-compass-set-with-swing-arm-protractor) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-05*
