Q: I received the luminous sand but it didn't shine. Is it invalid?<br> &nbsp;<br> &nbsp; Answer: Pebbles are light-storing products. The principle is to absorb light by absorbing light source. Each time the light is 8-12 hours, the first 1-2 hours are highlighting period and then continue to emit light. The product received did not emit light because there was no light source absorbed during the logistics process. Just take the sun or the light for a while and you can re-light it.<br> &nbsp;<br> &nbsp; 2. Q: Why did I have a sun in the daytime and still not lit at night?<br> &nbsp;<br> &nbsp; A: Because the principle of luminous light is to emit light while absorbing light, that is to say, it also starts to emit light during the process of light storage. If it absorbs light during the day, but after the twilight time, after the highlight period of the luminous light, it can only be seen slightly. Weak light, but when you turn on the light and then shine it, you can see it is very bright.</strong></span></p> </div> <div style="text-align: center;">&nbsp;</div> <div style="text-align: center;"><br> <br> <br> <br> <br> <br> <br> <br> <br> <br> &nbsp; </div> <p><span style="font-size: 0.0px;">Description loading</span></p> <div style="font-size: 0.0px;margin: 0 auto;color: #ecf0e1;">&nbsp;</div> </div></div>
