I work with wood a lot so I'm always happy to get my hands on these items. I build cabinets all the time and these squares can make the job easier and tidier. They're packed pretty well, in lots of foam. They look good and are well made. I used a square to test for "perpendicularity" and it is correct. And of course they are easy to use. Everything about the packaging is durable. I'm sure it will be the last one than me. I have nothing bad to say about iron. Unfortunately there are no instructions or any markings in the box. Of course, that's easy to understand, but when nothing's included, it seems like they care more about selling the product than they care about their customers. /rant While not expensive, it's a little pricey for what it is. One star minus between the price and the lack of instructions or instructions. All in all this is a good product. If the price suits you then I recommend.
