Mr. Pen Professional Compass: Perfect for Making Accurate Geometry Measurements

Michael: This compass worked well but I probably should have done my research a bit better. We bought this as a math compass and she doesn’t love it because it is it easily adjustable. Though the color is adorable which is why I got it. Plus the math oriented compass was much more expensive. But I got what I paid for!

Jerry MartisJerry Martis: Advertising said 8 inch circle size, however 7 inch is max. I have purchased many of this vendors products and been pleased with all to date, even this compass is excellent, just need to correct the possible circle diameter to 7 inches

Glitter LadyGlitter Lady: This compass is a great tool for Artists, Painters, UX/UI Designers, Graphic Designers, Illustrators, and art students to have in their tool kit. This compass helps to accurately draw shapes, such as the circles in my photos. I can draw individual circles and overlapping circles a lot faster and more accurately, with this tool. As a Graphic Design student, this compass makes drawing geometric shapes much easier. By using this compass, I feel more confident about the end result of my hand drawn pictures. By using this compass, I am able to present to my professor and to clients/customers art work-drawings, paintings, pictures that are worth to put on display to look at. The color rose gold is a unique color option, that is not available by the competitors. the rose gold color fits my girly personality. The metal is definitely hard. The pencil leads are easy to insert. The tubes for the lead and the clear carry case are all convenient for organization.

The first photo shows 3 circles of different sizes. i had to test the maneuverability of the turn wheel. I had to test the quality of the pencil lead. I had to test the width from narrow to large, for drawing these circles. The...

M.: One of the kids needed one for school and the one he had been using was horrible in that it would not stay at a fixed size and the circles came out as ovals. I went looking for a good quality one like I use and this one has all the features of my professional drafting one but at a fraction of the price. Its held up very well and it actually stays set on a diameter so you can draw circles.

Amazon CustomerAmazon Customer: Compass arrived today in terrible condition bent badly. Bow compass does not open past 3" 1/2. The claim of 4" compass is a lie, maximum circle size is 7". Severely disappointed will be returning.

StewmeStewme: Too much play in the screw setting and the spring tension is too weak so it won't keep it's setting. If you open it too wide the whole thing falls apart and is VERY difficult to re-assemble. On top of this, the tiny screw that holds the pencil lead was loose in the package, luckily I discovered it before it got lost. I threw it away and bought a much better one for almost the same price.
