The square arrived quickly and was well packaged. The problem is that the square will vary from about 1/16" to 1/8" - the yellow ruler with dimensions was set too deep into the metal base during manufacture. Grids don't start from zero. Disappointing. I like the ruler's legibility, its weight, and its size. This would be one of my most used tools if it was more accurate. 1/8" is too much. I don't want to calculate an error every time I use it.
