Mr. Pen- Professional Geometry Set, 7 pcs

For the price, this is the best compass kit. When drawing a circle with a compass, you want the compass to hold the width you want. You want the point to not move so one swipe around your done. This compass has a gear that opens the width, thus won't change during use. I've purchased others in stores and you spend more time fixing what went wrong. One and done. One circle around, and its done.

Warning! Open the set on a towel. Three of the very tiny screws and wheels were loose in the box. If lost in carpet..say goodbye forever! Otherwise a very nice set wit quality tools. My best guess is a $1 an hour employee got frustrated and said "screw it" before giving up during a very tedious assembly.

Happy with the quality of the smaller compass and accessories. The smaller compass holds the setting pretty well. The pencil adapter works well with mechanical pencils and allows for consistent fine lines. The larger compass screw and pins have play that allows for some movement. It should hold position fine as long as you are careful to not put inward or outward pressure on the arms, much like the freely adjustable style, but with less risk of losing the setting. I've used the smaller compass a bunch for making mandalas on 4x6 cards and have been quite happy with the accuracy, but have not used the larger compass. Overall, the $13 is more than worth it for the smaller compass, sharpener, extra leads, and pen/pencil adapter if the larger compass does not work out.

Buen producto y de buenos materiales

this is a real quality instrument with a beam to increase the working radius. you may need to watch a video on how to use this, i do not have one. with this, you can do home remodeling to scale (architect ruler needed), home yard improvement/landscaping and many other things. comes in a good case, and i would give this as a gift if i had any friends (who would use it)

Inexpensive compas that can be used as a beam compass with an attachment arm. Some metal and sturdy enough for lots of years of use I use it for application of oil paint

*Edit* I would like to first say that the customer service is the best I’ve dealt with. The company does take great pride in their products and are not just sending cheaply made junk. If there’s a problem then they want to know and want to fix it. I hope the issues are addressed and I would definitely purchase from them again. I think I would avoid compasses that have plastic parts that are important components though. I knew at this price that it wouldn’t be made from the best materials or have precise, German like engineering. I was certain that it wouldn’t last for years or even a year at best. At the moment I couldn’t really budget in a high dollar compass so I decided on this one. I bought this around July 8th of 2022 and had immediate regrets. As shown in my video… the inserts that hold the thumbscrew are really loose. The thumbscrew is also loose at certain lengths which has to be adjusted regularly. I say regularly like I’ve had it for awhile but it’s been less than one month. It didn’t slowly start getting loose… it came loose and has progressively gotten worse. It probably wouldn’t be too bad if it wasn’t a precision instrument. Well it is a precision instrument and that means loose parts are a huge problem. It isn’t all bad though. The small compass seems to be kinda decent and would be good for something small, really small. I haven’t used the extension arm mainly because the big compass doesn’t really need more variables to throw everything off. Everything else is pretty basic. I’m always exited when there’s a free sticker and this one came with a mustache one. While that pleases my sticker collection, it’s not enough to gloss over the loose compass. There were a couple of other inconvenience like the lead wouldn’t come out so I could sharpen it. Even after removing the screw that hold it in… I still had to get a pick to get it out. I was excited about the pen attachment because I’ve usually just taped a marker or pen to one of the arms. This was going to be a game changer for inking my drawings. While it does well for pens, it was too small for a sharpie. When I say too small… I was able to force one in it but it took some real effort and a little sandpaper on the sharpie. If only the compass was this tight. There is also a plastic screw on the bottom of the attachment to angle the pen for some reason and it’s awkward to get to. It doesn’t really matter because it’s loose too which makes the compass even more inaccurate. Overall it’s just an unfortunate buy. I had relatively modest expectations but was disappointed when I realized I would have to make constant adjustments and still not get the precision I get from a cheap, flat style compass like I used when I was in school.

This is such a great set. Im using this for drawing and there are so many great options.

I'm really happy with this geometry set. The quality of the tools is really good and they feel much better than the basic geometry sets I've used before. I've been using it a lot for my architecture work, especially when I need to draw circles and do accurate drawings. The compass has been particularly useful and has helped me make lots of circles accurately without having to struggle with the tool. I've used the set quite a lot and so far it has worked really well for me. I also like having the different tools together in one set, which makes it convenient when working on drawings. Overall, I'm very happy with the quality and performance of this set. I'd definitely recommend it to students, especially anyone studying architecture or doing technical drawing.

This is a very nice package! The compasses are surprisingly strong even though they look quite lite. Even with the extension in use, circles meet at the overlap. The point from the smaller one can be put in place of the lead in the larger one to create a divider. I'm extremely pleased with Mr. Pen! The only thing that might future proof the set would be a few extra wheels and pins for the clamps (at least the pins). They are very small and if dropped are difficult to find. Fortunately I did find the ones I dropped, but if not found the set would become pretty useless.

El juego de brújula (compás) acá en México, me pareció de muy buena calidad, además viene con algunos accesorios muy útiles y que no había visto anteriormente. Lo recomiendo ampliamente.

The quality of this metal compass is very good. It's packed very nicely in the box. I would definitely recommend them to everyone.

Excellent quality. I am very happy with this product.
