Max Glow products are made with a safe, high quality photo luminescent material that is both chemically and biologically inert. If your out and about in the dark, they can be recharged in seconds with a bright flashlight.
Fun for dark nights and early mornings. No batteries required to make them glow, leave in the light for 5 minutes to get around 30 minutes of bright play time fun. Shine your mobile phone torch on the ball to get extra charge.
