This is a beautiful metal square ruler. I use it to make metal parts. I like the black color as a contrast to the aluminum and steel (easy to find on a crowded desktop). I have used pencils, sharps and pens with good success. The only problem is an error in the screen printing or embossing on the scale. I don't use it to measure, so it doesn't really matter.
