Luminous products have a better effect of absorbing ultraviolet rays. They can be placed in the sun or in places with ultraviolet rays outdoors during the day, and glow in the dark, and repeat this cycle.
Please absorb the light under the light after receiving the goods, and then you can see the glowing effect in the dark.
The brightness of the luminous light will be different depending on the intensity and duration of the light. After about 30 minutes of exposure, it can emit residual light for several hours.
When there is no ultraviolet sunlight at night, you can put it under the light to absorb light. There is no need to deliberately expose it to the sun. As long as it is exposed to the light source, it will start to glow in the dark.
