The IsoFlex stress ball is a popular therapy ball, although not your typical stress squeeze ball.  It is not made from foam, or gel filled but instead is filled with micro beads.  However it can be used for strong rhythmic squeezing because it is double lined for durability.

Measuring 2.25 ins in diameter, this stress ball is slightly smaller than some but still fits well into the palm of your hand. It is made from latex which makes it very comfortable to use and comes in various colors.

Whilst we like this stress ball, the micro beads contents mean that if it does burst, it is unsuitable for children and so should only be used by people older than 8 years old.
