    Great initially but after just one year, the letters and scale marks have worn off. It's basically a disposable scale. Will not by again.

    These four inch scales are hard to find but are perfect for our needs. We use these while working on a clipboard so the size is most important. The aluminum is sturdy, the markings easy to read and the small rubber strips make gripping easy even with cold hands. Perfect!
