I am not exactly sure how these pads work. I have never tried them. I think you peel off the shiny part of the pad and it has a sticky back that can be used as a lint remover. I am not sure if they can be reused or not. I don't exactly know if they will ruin your clothes. They just have been sitting in my linen closet. There are some marks and folds on them, but I don't think it will affect their effectiveness. If you are interested in these, I am willing to sell with with free shipping if you combine them with another item.
