These glow in the dark series of scarves are like passive torches, incorporating smart yarns of phosphorescent yarn that can be charged up under a strong light before emitting light for up to 4 hours. Wear in the dark.

Dear Jennifer Robertson,
I like your scarves very much!
How do they glow? All the glow in the dark products I have seen yet have this greenish shine. But yours seem to glow all white.
Curious greetings from Switzerland,

Hello Tabea, the scarves are woven with a glow in the dark yarn that forms a pattern in the cloth. When put under a light source this charges the yarn and it will glow for up to a few hours at a time.
