Tenare 6 Pcs Plastic Clear Math Set Includes Protractor Triangle Rulers 12 Inch 6 Inch Straight Geometry Math Transparent Ruler Measuring Tool for School Office Home Supplies

No issues, came as expected and has worked perfectly for me. They are sturdy and a great price for everything you get.

Daughter needed the one for math class but love that it came with all the others too!

They are see-through which is cool because I can see under it. They seem solid and the notches seem accurate enough.

I found these instruments useful for making preliminary construction diagrams, being reasonably sturdy, and accurate, and would make a good set of instruments for high school, or undergraduate university math/science students.

Excellent quality

This little assemble is perfect for those whom don't want a bulky set, great for throwing in a kit and tossing in your backpack.

I loved that all these measuring item came together... did not have to piecemeal my purchases

I was using one of the triangles for the first time today, and I noticed something really strange. The inches are divided into TENTHS. That's really strange and not at all normal. Inches should be divided into EIGHT or SIXTEENTHS. I also used one of the rulers and it was divided correctly. Go figure...
