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. The company later expanded their 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.
