How do you remove a stuck tin box lid?

To remove a stuck tin box lid, first try to gently tap around the edges of the lid with a rubber mallet or the handle of a screwdriver to loosen it. If that doesn't work, run warm water over the lid for a few minutes to expand the metal slightly, then attempt to twist it off. Alternatively, you can use a flat-head screwdriver to carefully pry the lid up, taking care not to damage the box. Always use caution to avoid injury or damaging the tin.
