It arrived very bent because it didn't feel very good when it was transported in the suitcase. I was able to bend it into a usable shape, but its accuracy still left something to be desired because, despite my efforts to correct the warped metal, it wobbled on a flat surface. The cork backing was not damaged so it stayed in place as expected. I've used it to fold some advanced paper airplanes so it works as expected. Not the best, but I'm doing my best to make the best of the situation. I believe if a steel ruler doesn't stand up to shipping then it doesn't deserve full marks.
