The blue Nee Doh Stress Ball is a colorful and squishy squeeze ball made of silicone and gel. With a unique feature of color change, this stress reliever can change from pink to blue to yellow and back again. The ball also returns to its original size and shape after being squeezed, making it a fun and quirky way to release stress and fidget. Made by Schylling, this 3-inch tall ball is both lightweight at 2.7 oz and easy to carry around for on-the-go stress relief.
