3 Colors Glow in The Dark Necklace Steampunk Hollow Pendant with Chain for Women (Lotus)

Charge Guiding
The necklace can be charged by white bulb, sunlight and UV flashlight. For easy to use, you can charge by your smart phone app "flashlight". You can charge the necklace for a moment, when the glow light fades out, you can charge it again, the necklace can be charged over and over. UV-light works great with glow in the dark items and charges it a lot faster than normal LED or sunlight does! When fully charged it will glow brightly for the first hour (which is a lot for glow in the dark materials!) and after that it fades out slowly in the following hours. But no stress!
