Core Glow products are eco friendly glow in the dark pebbles and aggregates. The pebbles are used for glow in the dark fun indoors and outdoors, wherever there is light (so the pebbles can charge). The aggregate is used in hardscaping, concrete, concrete countertops, pools or even fish tanks! 1 inch plastic pebbles come in 1 pound bags at $20.00 each.
