The material of products

Miraclekoo UV Beads are extremely sensitive to natural light and change color dramatically from white to various colors when exposed to sunlight or even on an overcast day. Containing trace amounts of a photochromic pigment that are sensitive to the ultraviolet component of daylight, the beads have many different uses ranging from scientific testing of (ultraviolet) sun block materials to the creation of 'smart' jewellery.They need to be put under the ultraviolet first until they turn into different colors. Then they will glow in the dark. The stronger the ultroviolet, the brighter they will glow in the dark. If they don't put under the ultraviolet first, they will not glow in the dark.
