A clear bracelet that turns a color when sunlight hits it, then fades back indoors. It is a novelty party favor rather than a piece of fine jewelry, so it suits giveaways, event favors and kids more than everyday wear. Rivals in this space are silicone bands and glow-in-the-dark bracelets; this one reacts to UV specifically, which makes it a small interactive trick. Expect a lightweight, simple build, not a durable heirloom.

This is a customized bracelet that reacts to ultraviolet light. It starts out clear. When it is exposed to direct UV rays from the sun, it changes to a color.
