Features: 1. When you receive the parcel, please put all the gravels in the sun for about half an hour to make them fully charged, and then you can watch them in the dark, and they will emit bright light. 2. In a completely dark space, they will continue to glow for about 2 -3 hours. They can be recharged and illuminated repeatedly. 3. If you want it to shine all the time indoors or outdoors in darkness, please install an LED ultraviolet black light on it. It can be applied to indoor and outdoor floors, making terrazzo, decorating pools, bars, vases, fish tanks and aquariums. It can also be used to decorate garden flowerpots, mark paths and walkways or as the boundary of plant beds or ponds. Note: after receiving the product, put it in the sun or light to absorb the light. They only emit light, absorb and store the energy of sunlight or other light sources, and emit light in a dark environment. Nocturnal stones absorb enough sunlight or other artificial light during the day and glow at night or in any other dark environment. If they are not bright enough, please use the lights again. The product cannot be used without light absorption. Please follow this procedure.
