I love these glow in the dark stones. I filled up a nice glass jar halfway with these. Then I put in a flameless candle (make sure it is switched on), I add more stones around the candle. I set it on the table on my deck. I now have a very nice centerpiece for my outside candle. It has been a conversation starter. My neighbor saw it and asked me to make her one!
You can use these for walkways and flowerbeds also.However, I think you'd need A LOT for a walkway.
