So, definitely a versatile product use. Using a tape measure was cumbersome, and since I do not need an actual measurement number, just a constant pt A to pt B, this is a perfect tool! Such pretty color (rose gold)! Metal feels sturdy, but not heavy! Twelve sharp lead replacements, two metal point replacements with extra screws and washers. A cute mustache sticker! And a sweet 'thank you' from Kaelyn. 🩷 If you sculpt nails, definitely buy this for consistent lengths. Review: Shop with Mr. Pen and you will be completely pleased! - I have always been 100 percent happy with every product from Mr. Pen. I have been their customer for years and have been pleased with the price, the quality and even the packaging. I even get a smile from the Mr. Pen sticker that is included with every delivery. This protractor is of the quality and usefulness of a much more expensive product. I love that my small purchases help to support an American small business and a group of teachers who saw the need of students and they created this high quality company. Support this company! Be happy that you have saved money and have purchased a product worth the price. ## Features - Precision Geometry Compass With Spring Bow Head And Center Wheel Prevents Unintentional Leg Movements - All Metal, Nickel Plating Compass, Lifelong Satisfaction Guaranteed - FREE LIFE TIME Lead Replacement, Contact us via desertcart and we will ship them to you for free. 2 Pieces Of Spare Lead Includes in The Package. - Packaged In A Clear, Reusable Pouch.

You can just message us on Amazon or email us and we will ship you extra lead anytime. free of charge. **Q: How small is the smallest drawable circle?** A: I just drew a circle in the all-the-way closed position. It was 5/8". **Q: No matter how much i tighten the screws, both the lead and needle push up when i try to draw a circle. how can i prevent this?** A: When I replace the lead I make sure the screws are loose enough for me to slide the lead all the way to the back of the compass. Then tighten it slowly and make sure the lead hasn’t moved while I tighten it more. I had the same problem when I first replaced the lead but found the right way to tighten the lead. **Q: Can you use chalk instead of lead?** A: No. The holder on the compass isn't big enough. If you wand to tape chalk to the arm it might work, ## Customer Reviews ### ⭐⭐⭐⭐⭐ Measuring sculpted 💅 nails *by T***7 on July 2, 2026* I am using this compass as a measuring tool for measuring the length of acrylic/gel sculpted nails; width of clients nails that need tapering.
