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!

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.

I bought these to give to high school age kids at our local donation center. They do a wonderful back to school program that benefits all the kids in our area. High school age kids usually get overlooked so I tried to buy items that would help them out.

I thought I was getting three protractors, when I actually got three SETS of protractors! This was great, as I constantly misplace them (which was why I was buying ANOTHER set!) They're sturdy clear plastic and as accurate as any like product I've found. You get three of each, a 4-inch protractor, a 6-inch protractor, and a 6-inch 360 degree protractor. Excellent fit for my needs at the time, and an excellent value for the price!

I was especially looking for a 360 degree protractor for programming the Sphero Bolts I purchased for my grand children. It will be great for setting angles greater than 180 degrees & for teaching points of the compass. The larger 180 degree protractor will be is great for most geometric drawings and the pocket sized protractor for smaller figures.
