Mr. Pen Geometry Set with 6 Inch Swing Arm Protractor, Divider, Set Squares, Ruler, Compasses and Protractor, 15 Piece Set

This is a good product for a good price. The company even wrote me a hand written thank you card. It's the little things. This small business will continue to get my business!

Comes in a flat, sturdy, convenient case, everything fits into it perfect and it doesn't occupy much space. All of the tools work great, the pencils are good quality and everything works great to this day.

The overall set is good but there is a design flaw with the compasses, the one with the twisting had a design flaw where if you open it too much, it becomes loose and hard to draw, the other compasses open too easily and shifts midway through when drawing an arc, the mechanical pencil is kind of bad because the lead doesn’t really work, the protractor asl so has a design flaw where you can’t draw the full ray, it was pretty easy to use. It’s very portable and durable and easy to organize as it comes in premade holes

Good quality, and offers many measurements! Great addition to our homeschool Math collection.

Some tools seem duplicative, but set is decent and useful.

Ordered as a gift for my granddaughter and she was very excited that it has so many things in it she will eventually use. I was initially only going to order the half moon template and the protractor found the cost of those was going to be more than just ordering this whole big kit! So definitely take that into consideration when you're ordering.. This was the more cost-effective method that I found..

I would consider my three star rating on this review being generous I received the Mr. Pen- Inclusive 15 Pcs Geometry Set in today's mail. Upon opening the set, I am sorely disappointed in it. The main reason I bought this set, is that in the question/answer area it stated that it held most pens. I was hoping to use the compass with the adjustable bracket to hold Micron pens for drawing circles when I do Zendalas. First of all, The only drawing pens I have that will fit the bracket are the slim Le Pen by Marvy, Staedtler Triplus Fineliner, and this takes some work to wiggle into the bracket, and Stabilio Pen 68 and 88. I was hoping the Staedtler Pigment liner, Sakura Micron, the Faber-Castell Pitt artist Pen and Sharpies would fit into the bracket. None of this fit, The screw on the bracket is all the way out. It is the bracket size itself that will not allow these pens to fit into the bracket. I also tried regular pens. The Papermate 1.0 M pen and the Bic round stic medium pen will fit into the bracket. The Bic Atlantis, Bic Velocity and Papermate Ink Joy pens will not fit into the bracket. In other words, only very slim pens will fit into the bracket. What also set the tone poorly, was upon opening the plastic zip type bag this set comes in, the plastic piece that opens and closes the top of the plastic bag came off, and would not go back on. Th pieces are very tightly crammed into the plastic bag, This has left scratches and that looks like the beginning of a crack in one of the rulers. The numbers on the smaller protractor have already partially rubbed off in some places. I would not expect this for something that is new and has not been used yet. Both triangular rulers are scratched. One of the compasses, I am not even sure how it would be used. This compass has tow solid metal points on it, with no space for any led. Be aware that all pieces in this set, with the exception of one protractor are very small sized. I have never seen compasses made on such a small scale as the ones in this set. These are sized more for a five or six year old hand size, and not high school, college or adult sized hands. I am also not sure how well they will hold up with the plastic piece that holds the two arms of the compasses together. The way they were jammed into the plastic bag, I am not even sure I can get all the pieces back into it. My advise would be to keep looking. There must be better sets out there than this one. I don't have a car, and need to pay for a driver, whenever I need to go anyplace, so this makes returning this set not cost effective.

We had a Mr Pen set like this from a while ago and needed another one for another child. The 1st set is 4 years old and all pieces work well and have held up like new! The 2nd set came in a cool case which is compact and easy to store in backpacks, desks, lockers. Very handy and helpful for math as well as art. Blue prints and architectural designs as well! Highly recommend! Big bang for your buck!
