New 10 Pcs New Colorful Glow in The Dark Stones Pebbles Rock for Fish Tank Aquarium no.32

I got these for my daughters Glofish tank. They glow so bright for so long. We usually turn on the glo light for a short period of time before going to bed. Then when we turn the lights off. They literally light up the room. They are amazing. We have tried many glo products for her glow fish tank. And these by far glow brighter and longer than any of the Glofish products. Took a while for them to arrive. Think they actually come from china. I was a little impatient waiting on the shipment. But it was most certainly worth the wait.
