5 Pcs Metal Geometry Set, Math Drafting Ruler Kit- Aluminum Triangle Rulers, Protractor, 8 Inch and 6 Inch Drawing Ruler, Measuring Tool for School and Office (Metric and Imperial, Black)

I liked that these are metal, not plastic. A very nice set.

This set is fairly small, but that's exactly what I was looking for. I have a travel watercolor kit that fits into a slim tin box that I can slip into my back pocket. The painting kit contains everything I need for doing a small painting. The only thing I was missing was something to help me get straight lines and square corners when necessary. I needed something that would fit in the tin box where space is at a premium since it already contains a tiny set of watercolors in a case that's about as big as a credit card, pencil, sharpener, water brush, eraser, .05mm pen, a couple of small pieces of watercolor paper, and a half sheet of paper towel. The 3/4/5 triangle from this set is perfect. It's barely longer than 4 inches high and thin (less than 2mm), but not flimsy or flexible. It fits inside my tin, under the other items, and is so thin that the lid still closes easily. I like the fact that it's marked in metric on one side and inches on the other. (I prefer metric, but here in the States, most things are still in inches.) The markings are precise and extend right to the edge. Also, it's easy for me to see the markings because they're light colored on a black background. Additionally, I've had no problems with anything scratching or rubbing off after several months of use. I've also used the ruler and protractor. The case keeps everything organized when I'm not using things. I'm really happy with the quality of this purchase.

I like the small plastic storage case. The metal is good quality, thin & lightweight. It's easy to read and offers precise measurements or cuts. It's exactly what I was looking for. It's a good price point and functions well for my needs.

I have mixed feelings about this set of rulers and angle-related implements. I got it mainly for the protractor but was disappointed to find that it is very small, only 3.8 inches long at the base. And yes, it is 0.8 inch, not ¾ inch. I was shocked when I realized the Imperial measurements are in 1/10 inch increments for all these rulers. I have never seen that before. The bad part is that the tick marks are close enough to standard inch markings (1/8ths, 1/16ths) that if you aren’t paying attention, you will interpret them as 1/8 inch marks. As with the protractor, the two triangles are also quite small. The 30-60-90 degree triangle is 5-7/16 inch along the hypotenuse. The 45-45-90 degree triangle is about 4-3/4 inch along the hypotenuse.All the pieces except the protractor are marked in clear white numbers on a black metal body with metric on one side and Imperial (in 1/10ths of an inch) on the other. The protractor is clearly marked with white lettering on a black body but it is only marked on one side. The bodies are aluminum and are a reasonable thickness to make the rulers rigid.These are well made rulers. They would be better suited to working on small drawings rather than my plan of using them in a shop. They are clear, easy to read, and should be durable, but the scale is wrong for most of my applications and the protractor isn’t big enough to measure angles accurately across larger areas. Good quality but the 1/10 inch scale just won’t be useful for me. Maybe there is a specific discipline that uses this scale? If so, and the work involves small drawings, this is a great set, but not for me.

The quality of the product is exceptionally high. No more buying plastic that breaks easily. These are environmentally friendly and solid products that will last.

Awesome Purchase

The mm scale on the triangles is off. That’s pretty disappointing. See photo.That’s my main point. I’m picky.The aluminum with black coating is great. They are strong and won’t break in my backpack
