Photoluminescent Tumbled Gravel have the natural capacity to emit light in darkness

Our Photoluminescent Tumbled Gravel have the natural capacity to emit light in darkness. The glow in the dark stones exist in different colours of glow.The phosphorescent effect can last all night long, after the stones have been exposed to light a few tens of minutes.This decorative effect doesn't need electricity and requires a minimum of care. The photoluminescence lifetime lasts a great many years.Their possibilities are without limit, they can glow indoors or outdoors, as long as there is enough obscurity: gardens, bedrooms, ponds, pools, fountains, aquariums, vases...These little objects are harmless, non-radioactive and made of plastic.
