The 65mm Acrylic Ball is ideal for big multi ball stacks and pyramids! The smaller surface are of the 65mm ball makes it a little tougher for single ball manipulation but it is good for sleight-of-hand magic tricks.
The 70mm acrylic contact ball is the most popular for multi-ball tricks or single ball manipulation for those with small hands. Acrylic balls have minimal friction with one another making stacking tricks a lot more pleasurable. Acrylic balls are incredibly strong but can become scratched if repeatedly dropped on rough surfaces.
The 100mm is great for isolations and head balances. All our contact balls are 100% acrylic. Great clarity and exceptional prices.
