These gel-filled squeezies may appear ordinary, but they change colors as soon as you give 'em a squish. Available in six color combinations, these super-squeezable stress relievers offer you more bang for your buck. The custom Color Changing Gel Stress Ball is both unique and versatile, and it can fit any type of business promotion or charity fundraiser without being boring or generic! Few colorful stress balls even come close to the appeal of our round gel squeezies. And don't fret, because these multicolored stress relievers are non-toxic, environmentally-safe, and hand washable! Each gel squeezie comes packaged in a clear plastic clam shell for added convenience, so all you need to do is add your company logo!
