These Harry Potter 3D puzzle erasers are not only for fun but also practical. To use them, simply take out the eraser you need and start erasing those little mistakes on your paper. When you're done with the erasing, you can put the pieces back together to form the puzzle again. As for storage, keep them in a dry and cool place to avoid any damage. If the eraser gets dirty, you can gently wipe it with a clean, dry cloth. Just remember, these erasers are small, so keep them away from small children to prevent choking hazards.
