These balls are made from the same great acrylic with beautiful translucent colors, available in red, aqua, green and purple. 90mm Acrylic Contact Balls are good for isolations and most body rolling tricks. These are a little too large for multi-ball work but still have lots of surface area to help your ball manipulation. 90mm contact balls are very popular with people who find 100mm a little too heavy (the weight jumps up considerably by 170g) and those who want to create similar illusions but without spending the same money.
Sold individually and price is per ball.
