What is the first thing that come into your mind when you think of Stress balls? Personally I will link stress balls to stress. From the name, it seems like stress balls will bring me lots of Stress. To avoid that, some people actually called stress balls as stress reliever. This name is correct in certain ways. Stress balls do release your stress a bit when you squeeze them or throw them (aiming at human is not what I am recommending here). It is not soo wrong to call it stress relievers after all. But stress reliever as a promotional product name? It does sound a bit funny. No one would really consider stress reliever as a promotional product unless they know in advance what it is.
So our industry come up with a new name which total eliminate the word stress called squeezy balls or squishy shapes. They are cute names compare to stress reliever, but they are not common names among end users. Squeeze balls describe the biggest nature of stress ball, it is squeezable. However, depends on the material use to make the stress ball, some of the custom stress balls are not squeezable. Now after three names in one product, stress balls are still well known as stress balls. If it brings you stress, try to kill it by squeeze it as hard as you can go.
