We are selling stickers what do not need special light to glow. These are the real ’Glow in the dark’ stickers. If you charge them using the sunlight or artifical light source (Black light is the best), they will glow in the dark.
The glowing can remain for 3-4 hours or even more depend on the charging. They comes only one color (white, what glows green in the dark).
If you want this sticker material to one of the puzzle that is not listed here, please contact us, and we will gladly create it for you!
