Glow-In-The-Dark Garden PebblesThe new Glow in the Dark Garden Pebbles are non toxic and eco friendly stones that could highlight your plants and space. These decorative pebbles are the bright lighting choice that uses no electricity or battery power. They absorb light throughout the day and then slowly release the light as an afterglow throughout the evening. The pebbles can be used indoor and outdoor, in aquariums, gardens, vases, pot plants and more. The list goes on and on!
