Zeekios Cirrus Juggling Balls feature a Lycra-based outer shell, and are filled with seed for just the right amount of "pop."
Cirrus balls have four panels, and are uniformly round and moderately firm. The outer shell is durable and has a bit of give to it.
The 140-gram Cirrus balls are about 2.75 inches in diameter.
Cirrus balls are also available in a slightly lighter and smaller 125-gram size.
