Disappointed would not recommend buying this it came in 2 weeks and i cut it open and found slime inside but after a week the slime turned into liquid all of a sudden and it would of done that in the stress ball was very disappointing i was good to have 5 sartsmnv fantastic and visually enticing just ok what it doesnt show in the picture is the net covering it has a large white plastic domed button on the back of the stress play ball so it is not completely a round ball
