Silicone bracelets are ring-shaped accessories made of silicone. Originating in the United States in 2005, the first yellow "LIVESTRONG" bracelet was launched by the Lance Armstrong Foundation, the foundation of Tour de France champion, in collaboration with Nike, to raise funds for cancer prevention. Made of environmentally friendly and non-toxic silicone, the product is wear-resistant, heat-resistant, and elastic, initially primarily for charitable advocacy.
As its popularity grew, silicone bracelets were expanded to adult and children's sizes, and functional materials such as negative ions and germanium were added to broaden their health benefits. Different colors are given specific charitable meanings: yellow represents support for cancer treatment, black and white symbolizes anti-racism, white symbolizes anti-poverty, blue represents anti-bullying, and pink supports breast cancer patients, among others. Their applications have expanded from sporting events to brand promotion, event advertising, and the medical field, combining decorative and functional uses.
