Using these disco balls is easy. Just hang them up using the included metal hanging ring wherever you want to decorate, like in a party room or on a Christmas tree. When using them, be careful not to drop or squeeze them too hard as the foam is delicate and the tiny mirrors might fall off. If some mirrors do come off, you can use the spare ones to replace them. To keep them looking good, gently dust them with a soft cloth every once in a while. Avoid getting them wet as it could damage the foam and the mirrors.
