To use these Pixie latex flexible ears, simply place them on your head where you'd like them to sit. They're flexible, so you can adjust them to fit comfortably. When it comes to care, avoid getting them wet as much as possible. If they do get dirty, gently wipe them with a dry cloth. Store them in a cool, dry place when not in use to keep them in good condition. Don't bend them too forcefully to prevent damage. Enjoy your magical look with these amazing ears!
