A lot of people and knock off brands are advetising glow in the dark bands but let me clear up all the truth. These do not fade after time and they hold their glow for HOURS. There are a number of offbrand companis who have glow in the dark rubber bands but their glow is inferior. Plus, the ones that are colored glow in the dark bands glow green and have a barely noticeable glow. Buy official and support the brand that started it all.
