#luminous hat

It's just exposed to the sun, why does it glow at night? The luminous beanie of MONALISHAMAGIC is not much different from ordinary hats in knitting, but it has an additional invisible ability. During the day, it quietly receives sunlight, and at night, the whole hat glows in the dark. No need to do anything, and no external force is required, it's like the residual heat left on the hat naturally. The more it is exposed to the sun, the brighter it gets, and its light depends entirely on the energy accumulated during the day.
