Ive bought many Mr.Pen measuring tools/instruments. And seriously, never not impressed. Great quality, attention to detail, friendly customer service (the hand written thank you cards are awesome), cool mustache sticker, and really just well thought out items. 10/10

Super heavy duty, heavy, high quality. Its as big as my forearm which would be fine if it wasnt so stiff. I find it difficult to open and a bit scared I will cut myself

My son decided, when he saw a compass on his school supply list, that he wanted "one of those old school ones because they look cool." Mr. Pen exceeded our expectations with this compass. Great quality, durable, functional and esthetically pleasing. Will definitely be buying more Mr. Pen products in the future!

Mr Pen 8”compass The mustache sticker is going on the tool box!! I was able to draw a 45/64”(a little bigger than 5/8”) circle with a round pencil with no flats on it w/ a 9/32” diameter pencil. When I opened it all the way I got a pencil mark from the point out to 9-5/16” or 18-5/8” circle. I guess you could push the pencil out further and get a bigger circle but with the pencil and pivot point at that angle it would be difficult and the pencil wouldn’t be on its point. Just get a bigger compass or a different drawing tool. When I first opened it the tool was very stiff to open. Once it was open I worked it back and forth a few times. I set the arc under the thumb screw and set it for tight 2” circle and drew a bunch of circles and when I went to reset it I realized I didn’t tighten the thumb screw but it held a very tight tolerance to the 2” circle. That speaks to the tight tolerance this is made. Everything about this is heavy duty and wouldn’t hide this with just woodworking tools, it’s quality for any trade.

The attachment that holds the pencil came broken off making the whole apparatus useless. Also the pencil holder was too small to hold a pen.

Definitely industrial in its make, which is what I wanted. I would buy a smaller one if they made it, and I think others would too. I am now shopping for another though, and that's because of the small pencil/pen holder. The design is great except for the diameter of the pencil ferrule. It has a screw-down knob for securing the pencil, so why is it designed so small? Recommendation to the manufacturer: increase the size of the pencil-ferrule, so mechanical pencils and pens can fit, even if you need to slightly lengthen the set-screw... and make a 6". Due to these oversights, I'll have to find one somewhere else.
