The Koosh ball is a toy ball made of rubber filaments (strands) radiating from a steel-bound core, patented in 1987 by Scott H. Stillinger. Stillinger named the toy "Koosh" after the sound it made when it landed in his hand. The company later expanded its product line to include 50 other Koosh-related products, including keyrings, baseball sets, and yo-yos.
The ball consists of about 2,000 natural rubber filaments, and has been released in a variety of color combinations.
As of 2020, Koosh balls are manufactured by PlayMonster in cooperation with Hasbro. They have introduced a range of new product lines, including Koosh Galaxy and Koosh Cameos.
