Sandblast sticker for glass or any surface, personally I stuck it on my refrigerator which has an inox front for protection from scratches made by my little one as he rolls his toy cars anywhere. No need for soap, it has its own adhesive on the back. I stuck it and removed it several times, it doesn't leave any traces of glue and sticks well. It requires a little skill in placement to avoid air bubbles and looking bad. I am satisfied.
