For the stressful hours at work the anti-stress ball Bert helps to release stress and make one smile. The little chubby  man is made out of a material that can be squeezed and then automatically puffs up to a normal Bert size. With increasing popularity of the little anti-stress doll, several versions of the doll wearing different costumes are now being made. Even keyrings are purchasable now. Massimo Indrio is the creator of Bert’s good looks, and he makes sure that the friendly face of Bert can be found on every version.
