Using these disco balls is a breeze. Just hang them up with the included 2' hanging strings wherever you want to add some sparkle, like in your party venue or on your Christmas tree. When it comes to maintenance, keep them away from sharp objects to avoid scratching the mirrors. If they get dirty, you can gently wipe them with a soft, dry cloth. Also, store them in a cool, dry place when not in use to keep them in good condition.
