Light Up DNA Ball 12-pack not only lights up your life. It gives you enough balls to share. Because “sharing is caring.” And everyone you know is stressed out and looking for relief. This ball combines a trio of features to stimulate the senses. First an ultra soft, flexible, thermoplastic, elastomer cover. Nestled inside are soft, translucent mini spheres in assorted bright pastels that invite squeezing. In addition, a larger LED ball flashes when compressed. Fingers become more flexible and hands stronger from kneading the ball. Squeezable balls that light make ideal distraction toys. Not only for children but also for adults needing respite from a stressful situation. Measures 2 1/2″ diameter. Is a Light Up DNA Ball 12-pack more than you need? Not a problem.
