As the number of times the bracelet rubs against with other objects increases . The words on the bracelet will fade away gradually . design rubber bracelets can be solid, swirled, segmented, glowing and UV. I think most people know much about solid, swirled or segmented but glowing and UV. Let me explain. Glow in dark silicone bracelet can glow green or blue after absorbing strong light energy under the effect of glowing powder which is green to human. The glow will fade graduallydesign rubber bracelets in about 3h depending on how much light it absorbs. It is the best one for night event. A UV silicone bracelet can transfer it’s color darker under sunshine when absorbing UV light. It transfer to purple or blue normally which indicating the strength of the UV index. Wearing it on the wrist is a good way to avoid long time staying under strong sunshine. We add UV powder which is also green as silicone in production.
