The main raw material of luminous stickers is Photoenergy storage luminous powder, and Photoenergy storage luminous powder is that fluorescent powder stores the light energy after being exposed to natural light, sunlight light, ultraviolet light, etc. After stopping the light irradiation, it is slowly released in the form of fluorescence, so light can still be seen at night or in the dark, lasting for several hours to more than ten hours. So please try your best to let it be exposed outside to absorb the light after receiving it. Don't have something to block it. Only after lighting can the luminous absorption become brighter and brighter, and the longer the time is!
