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 ### ⭐⭐⭐⭐⭐ Recommend *by on Reviewed in the United States September 28, 2026* Great price for good quantity and quality. Sent with nice handwritten note. Super thoughtful! ### ⭐⭐⭐⭐⭐ Better than expected! *by on Reviewed in the United States August 17, 2026* This was a sturdy Item with refills of led and pointer. The best surprise was it had the cutest little mustache from the Mr. Pen Brand. Which has been a big thing in our household for the past few years. A+ ### ⭐⭐⭐⭐ Good for Price, but flawed *by on Reviewed in the United States July 21, 2026* Works pretty well, and seems good for the price, but does not work near it's maximum advertised size. 3.5" - 3.75" inch radius is a more accurate maximum, above that it tends to fall apart ## Frequently Bought Together - 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 - Quilters Dream Natural Cotton Request Batting (60'' x 60'') Throw - Mat Board Center, 10 Pack 8x10 White Backing Boards, Cardboard for Arts, Prints, Frames, Photos and More --- ## 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.ni/products/207801654-professional-compass-for-geometry-extra-lead](https://www.desertcart.ni/products/207801654-professional-compass-for-geometry-extra-lead) --- *Product available on Desertcart Nicaragua* *Store origin: NI* *Last updated: 2026-10-16*
