Using these disco balls is super easy. Just hang them up using the provided 2' hanging ring wherever you want to create a festive atmosphere, like at a party or on your Christmas tree. When using them, make sure to hang them in a place where there is enough space for the light to reflect properly. For maintenance, you can gently wipe the balls with a soft, dry cloth to keep them clean. Avoid getting them wet as it may damage the foam and mirror materials. Also, be careful not to drop or hit the balls hard, as this could cause the mirrors to break.
