At less than $2 each, these are a great value for money.If you're worried about quality for that price point- don't worry, these are really nice.The plastic is sturdy, the swing arm swings easily (and 360 degrees), and they seem well made enough for many hours and many students to use.They're a nice size, at 4 inches, and the markings are clear and easy to read.Super nice.

These are great protractors. They are well made and really easy to use. And getting 10 of them for such a reasonable price is fantastic. I like that they are smaller than some of the protractors out there so it makes it easier to use. The plastic is very clear and the markings are easy to read. I think this is a great set and would definitely recommend.

If you're looking for a solid set of protractors for the classroom, this 10-piece Swing Arm Protractor Set is a great choice. The plastic feels sturdy enough for regular student use, and the 360-degree rotation makes measuring angles super easy and precise. The 10cm circle size is perfect—not too big, not too small—so students can handle them comfortably.I really appreciate that this comes as a classroom set, making it convenient for teachers who need multiple protractors for group activities. The swing arm feature is a nice touch, helping with accuracy when drawing angles. Overall, this is a reliable and affordable option for any math class!

I'm a teacher in NYS and these protractors are great for the new state labs that we need to do. I had been looking all over for these and was so glad to find them. The notch in the arm off of the protractor is very helpful for making marks in the right place. I'm very happy with these!

I love the design of these protractors. They are small, which is great for measuring angles out of a text book. They are clear, so you can see the exact number to which the angle is pointing. The full circle means you don't have to turn the book around all over the place. And the arm help for measure angles that are quite small. A lot of thought was put into the exact features a math teacher and/or student would want and it was well executed.

This is a cool set of rotating arm protractors. My daughter was having a hard time using a typical half-circle style protractor because the lines on the homework didn't go to the measurement guides on the outside of the arc. These are perfect and just what we were looking for to help line up the lines in angles and triangles to determine the correct angles! It's nice that this is a set of 10 so my daughter is handing some out to her friends. Great deal for the money!

These are handy, little protractors, likely perfect for architectural drawings and small measurements of angles, etc. They are a stiff plastic, though not so stiff to make it hard to change the angle, they don’t seem likely to slip from the angle set while you draw.The size makes them convenient to carry and store, and the number of protractors included in the set means that you can get them for your whole team or have one in every room that you might use them. The center of the circle is set up such that you can easily draw the beginning lines of any angle or degree.Highly recommended!
