Turn down the lights and turn up the fun—this glow-in-the-dark Marshmello squishy ball is built for squeezes that don’t quit when the sun goes down. By day, it’s a soft, marshmallow-style stress ball with that ultra-satisfying slow-rise feel collectors love. By night, it transforms into a glowing pocket of fun that lights up every squeeze with an eerie-cool glow, making it just as entertaining in the dark as it is on a desk.
