I used the protractor and compass about ten years ago. I removed as much dirt as possible, but there are some parts I couldn't clean, so please refrain from purchasing if you are concerned. Also, the straight ruler (image 6) that came with the protractor set was used frequently, so it has significant scratches, dirt, and peeling of the pattern. I will include it as part of the set, but if you don't need it, please comment. The compass wasn't used much, but it has some scratches. Please understand.
