Great product at a wonderful price

These are perfect! Thick, good quality, great packaging and durable.I bought these because my daughter is in 4th grade. She is in a classical homeschool program using Saxon Math 5/4 and they have started doing Geometry and I thought she would have an easier time if she had proper tools.I picked this set because it had so many tools and it was the best bang for my buck. Just a few dollars and you get SO many. I thought the normal sized ones would be what we used but my daughter likes to use them directly in the margins of her book so the little one works perfectly.There are plenty of them too so I can keep one in a pencil bag in her at home binder, one in her pencil box at her school and an extra one in her backpack for a back up to have on the days she goes to school on campus and I still have a couple to that we keep at home. I like the different shapes and sizes too so I went ahead and put some in our math supplies basket and one in our Art Supplies closet.I'll be surprised if I ever have to buy anymore of these. There's enough for all four kids!

These protractors are really great for my third grade students. I like that they have that extra arm part. That is what really makes them easier for younger students to use. These are sturdy and effective.

These are snazzy and a decent price. However, not for younger students. My first day having them available and after giving firm notice to treat correctly, one was broken (unfixable) and one pulled apart (fixable) within the first hour. Not the toughest tool.

The size is larger than expected but worked out perfectly for daughter to learn to use a protractor. Sturdy and great quality.

Good for larger canvas paintings / design.

It should be noted that I have had this tool-kit for only about 2 weeks, so durability and sturdiness are a bit shy on a really good (years +) testing :)That being said, receiving 3 of each tool in the "9-piece" set was really nice as I use these kinds of tools both at home and in my studio at school; odds are I'll break or lose something too, so having a backup set is wonderful. As other reviewers noted, these are quite thick as compared to other products. My old protractor broke after many years of use, but it was probably half as thick as these (but these are not crazy thick; the plastic is simply solid stuff). So, I cannot see any reason that these tools will not last a lifetime presuming I don't do something stupid with them (e.g., sit on one - which is how my old one died) or just lose them.All in all, these tools are quite the deal, for children or adults. Hats off to Mr. Pen for being a company that still makes quality goods.

Although I love the ease of the moving arm on the protractor, my student accidentally dropped it on his desk and it broke. Only 1 day of use and broken. I'll have to look into sturdier protractors.
