INCLUDES 1 RANDOM COLOR BUBBLE TEA STRESS BALLS - These boba bubble tea drink stress balls are so adorable. The fruity drink comes in 4 different colors. These stress balls are unique because the outside layer of the ball is soft plush fabric material. They are a pliable squishy soothing sensory ball filled with a bunch of thick colorful water bead gel balls inside its elastic flexible skin. The colorful skin is so soft. When you squeeze the drinks, the jelly beads push out and around making the ball bulge and it makes it look like it is blowing a bubble. It is very soothing to feel the little gel beads, and it also makes a soft swishing sound to add to the sensory experience. 2.5" ball. These are nice because they protect the ball from being twisted or jabbed with fingernails so it makes them a little more durable for occupational or therapy settings. If the internal ball breaks you can add a new one.
