For being metal sanders they are absolutely perfect. I was a bit wary that they might be hard on plastic when sanding... but they are not. As long as you let the sander to work, it will take off all the sprue marks and undesirable bits leaving a perfect plastic surface that blends with the model. Highly recommended.
