3cm 100pcs Glow In The dark

The main raw material of a luminous sticker is photo-storage luminous powder(no radioactivity), and photo-energy storage luminous powder is obtained 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 irradiation, so that the light can still be seen at night or in the dark, and the duration is long. It can take an hour 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 day lighting 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)
