Luminous products have a better absorption effect on ultraviolet rays. They emit light in dark places during the day, and the cycle is repeated.

Please absorb light in the sun after receiving the goods, and then you can see the luminous effect in the dark.

Because the goods cannot absorb light in the express package for a few days during transportation, they must absorb light.

During the day, put it in the sun or in a place with ultraviolet rays outdoors, and shine in the dark.

The intensity and duration of the light are different, and the luminous brightness will also vary. After about 30 minutes of irradiation, it can emit several hours of residual light.

When there is no ultraviolet sunlight at night, you can put it under the light to absorb light.
