We use the highest quality glow in the dark material. Compared with regular sulfide photoluminescent pigments, it has 10 times higher and longer afterglow luminance as well as afterglow time. A beautiful gift for everyone!
When you are in a darker place appears this magic "turquoise" light! You have to charge it by holding it under sunlight a few minutes (or any light you have) before you wear it in a dark. It will gradually release its light energy throughout the night up to 6 hours.
