These light-weight string balls are easy to catch and grasp, and used in the Davis "Koosh Ball exercise" (described in The Gift of Dyslexia) to build balance and coordination, and for fine-tuning Davis Orientation, Alignment or Focusing skillls. 

Each Set includes two regular size (3.5 inch) balls.

Orders may be filled with classic Koosh balls or newer, latex-free Woosh balls depending on product availability.
