The main raw material of luminous sticker is photo-storage luminous powder(no radioactivity),and photo-energy storage luminous powder is after the phosphor is exposed to natural light, daylight, ultraviolet  light,etc.The light energy is stored and slowly released in a fluorescent manner after stopping the light irtadiation,so that the light can still be seen at night or in the dark and the duration is long. It can take hours to ten hours, so try to let it be exposed to the outside and absorb the light. The more the night  light is absorbed after the daylighting brighter, the longer the time. It is provided with double-sided tape. When you use it, just cut the double-sided tape into small pieces  and stick it on the wall. You can see the faint light from this luminous sticker at night. 70Stars and 30Moons(100pcs)
