This ruler is cute, and the metal material works well, but the measurements on the inch side are inaccurate. The inch and half-inch markers are fine, but the rest was divided using the wrong multiples. So there are twentieths instead of sixteenths, and tenths instead of eighths. The "quarter inch" is not the right length. It will mess up your work, unless you only need to measure by 1/2 inches. This product should be recalled.
