Before the first use, please expose stones to sunlight/ bright light at least for 2-4 hours. Tile these stones when they are exposed to the sun, to make sure each of them absorbs enough sunlight. The longer they absorb the light, the brighter gravels are, the longer the glowing time will be. The darker the environment, the brighter the stones shine If they don't expose to sunlight/ bright light, the stones will begin to glow and emit energy. So when they do not glow or bright enough in the dark, please put stones under the sun again.
