Glow in the Dark Swirl-StoNZ
Great fun for children - take them to bed if you are
scared of the dark.

I make my own glow in the dark polymer clay for these
Swirl-StoNZ with high quality photoluminescent powders. The glow will gradually
fade in the dark but can be recharged by exposure to sun or electric light for
at least 30 minutes (the longer the better).
