Balls are made of foam covered in small mirror pieces and measure approximately 5cm in diameter. Come with a silver loop for hanging. Please be aware due to the shape of the Mirror Balls a small amount of foam can be seen. Not for children under 3 years of age. These sparkly disco balls make a fun decoration for your 70's Disco party - hang them up around the room, add them to place settings or pop one in each favour bag for each guest to keep the 70s Disco funk going at home!
