NOTE: Since the mirror ball is made up by many small glass. During the air mail transportation,maybe some of them will fall off. Package included: 1PC Glass Rotating Mirror Ball ( Don't included Motor and the Lamps ) Diameter 20cm/8inch( Don't included Motor and Lamps ) Note: The package ONLY contains a 8inch disco ball, no motor or anything else. The product's interior consists of foam. The hanging ring on top is secured to the foam ball using screws and washers. Due to the foam material's susceptibility to crushing and breaking during transport, the factory does not fully tighten the screws during shipment. However, the washers and screws still firmly hold the ball and ring together. Even if slightly loose, the ball will not fall off when hung. If customers prefer a tighter fit, they can use a screwdriver to tighten the screws slightly after receiving the product (though excessive force is not recommended to avoid damaging the foam ball).
