Great little set, odor free and superb quality. I purchased these to help with field sketches. They are a great size and the non skid backing is a wonderful feature. These are small enough to use in survey field books.

Great Price for A Great Set. If you need a set look no further.

Wow. I am impressed with everything about this set. Compact, precise, and protected. Everything seems to be perfect except there were some labeling stickers that must have gotten peeled back in transit or packaging and which left some residue on the ruler. I scraped most of it off with my finger nail and the plastic didn't seemed phased at all with me scratching at the back of the ruler. I think this set will be a great set for years to come and will help me through engineering school.
The plastic seems like it is really good for this kind of application. I know that my staedtler set was so brittle that they cracked before I knew it. These ones hopefully will not meet the same fate but these seem to have been made of really high quality plastic.
The other thing about this is the case. The case has posts so that all the different pieces stay in place and don't just fly around everywhere. Great job Engineering, Designing, and Producing. I'm happy to have found such a great set for a such a great price. The only better option I could see is getting an aluminum set.

Very nicely made. I appreciate the extra attention to detail such as the small plastic pins inside which keep the contents of the case from sliding around when closed.

This is a good set. I have the Raymay and Sonic Nanopita sets as well. This set is not as grippy as the Nanopita. I like that the protractor begins measurements right on the edge. That’s useful in many situations. I also like that the Nanopita starts OFF of the edge; making it easier to get on the line in other situations. I also like that it has markings close to the center; useful when measuring angles with short lines. Nice of them to include the circle stencil. No real difference between this and the Nanopita triangles. I prefer the Nanopita though. The Raymay set (I bought them individually, not the set w the compass) is much thinner plastic, no grip, but the markings are very nice and the triangles are larger. All said, I find all three set have proven to be useful for different scenarios. If I had to only get one, I prefer Nanopita.

Really nice set. The anti slip backing works well, and the case it comes with keeps everything organized.
