The Rayminder UV Awareness Bracelet in Aquamarine adds an oceanic glow and the element of sun safety to your everyday bracelet stack. Each Rayminder UV Awareness Bracelet has a uv reactive bead that changes color when exposed to uv sunlight. The uv bead remains clear when inside or out of direct sunlight. As soon as the uv bead comes in contact with sun it changes to pink, purple, or orange ray-minding you to apply sunscreen and cover up every day.* Your Rayminder Bracelet is good for you and good for your community. $1 from every unit sold is donated to IMPACT Melanoma, a national nonprofit working to prevent skin cancer through awareness and education. One size fits most. *Our UV beads are for fashion and awareness purposes only, cannot gauge the UV Index, and should not be used for medical purposes. UV beads will remain a pink/purple/color until removed from sun.
