## Description

desertcart.com : Mr. Pen- Professional Compass with Lock and Free Life TIME Lead Replacement, Compass for Geometry, Spring Bow Compass, Precision Compass Math, Drafting Compass : Office Products

Review: Buy this compass! - Buy this one. You'll be impressed with quality. Bonus vials of a lead, spikes and the tightening wheels, as well as a cleaning brush were also included. I have never purchased a compass with all these accessories, not even the higher priced.
Review: Economical Yet Functional - This is not a professional quality tool and is limited on the min/max width. It's an economical tool that does what it's supposed to do. It doesn't lock, strictly speaking, but the adjustment wheel is firm enough. It comes with 10-15 replacement leads. Comically, two of the three little vials containing lead were empty and their contents were rolling around in the little bag. One of them still had the cap on it, so I have to think the person packing it was all out of effs to give that day and just dumped the required number of parts in the bag instead of trying to fix it. Two steel tip replacements, two little tightening wheel replacements and strangely no little screw replacements. A mustache sticker and a hand-written thank you note. It's stable enough for what I need to use it for. Doesn't have as much flex as some folks have reported. But if you're looking for a tool with tight tolerances and high production value for architecture or engineering use, go spend $100 - 200+ on a different product.

## Questions & Answers

**Q: Are extra leads easily available, if needed?**
A: Hi, Thank you for your question. 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,

### ⭐⭐⭐⭐ Does the job, but clearly a low-budget item
*by A***0 on May 10, 2024*

This compass does the job of a compass and does it very well. They even throw in some extra lead and a little storage pouch too! But while it does its job well, it doesn’t really scream “quality” at all. A big disappointment was when I first saw it and noticed it’s painted. Not anodized or coated, it’s paint and it’s obviously paint, with small lumps and uneven spots. In my opinion it doesn’t look much like the images other than in shape, with the color not looking close at all. The other point against: the adjustment screw is not centered between the arms. If set as wide as possible this is very obvious and is likely limiting the total amount of adjustment. It’s certainly not a professional-level product but then again it’s not a professional-level price either. It’ll draw a circle or an arc, help you measure things, and even scribe some things like I have, but it won’t win any awards for build quality.
