To use these Minnie Mouse collectible mini figures, simply pop open the pink plastic Minnie - shaped head to reveal the surprise figure inside. You can play with them on your own or set up a display to show them off. When playing, make sure to handle the figures gently to avoid any damage. For maintenance, keep them away from water and dust. You can use a soft, dry cloth to wipe them clean if they get dirty. And remember, these figures are for kids aged 3 and up, so adult supervision might be needed for younger children.
