You do realize these are BOY SCOUTS these gifts are for? Somehow, I don't think Disney Princess themed mirrors and tins are going to go over well.
i don't judge

anyway, plenty of non-princess ones, star wars, marvels avengers (hulk), spiderman, minions, teenage mutant ninja turtles, captain jake, paw patrol ....
besides, sanding the tins and painting them can be a project
