How do you get scratch off mirror?

To get a scratch-off mirror effect, you can use a special scratch-off material or coating available at craft stores or online. Alternatively, you can create one using a combination of black paint and a clear coat, applying the paint to a mirror surface and then scratching it off in desired patterns. Always ensure you're working in a well-ventilated area and follow safety guidelines. For a more professional finish, consider purchasing pre-made scratch-off stickers or films.
