OSOPOLA 150 PCS Luminous Stones - Blue Glow Rocks Decorations DIY Decorative Pebbles for Aquarium Fish Tank Sidewalk Garden Path Patio Terrace Lawn Yard Ornaments Blueness Cobbles Decor FD05BL150

I used these for a border around my rain barrel. They get full sun pretty much all day, and they glow great. For reference, the amount in my pictures was the 350 ct. i actually ordered 2 more bags because 350 sounds like more than it is.i would definitely recommend these if they will be getting full sun.

My kids really like these. We put them by the pond out back just for ambience. I’m surprised at how well they work after being outdoors for so long but they work great! They clean easily with soap and water when we’ve had a bad storm. They don’t fade. The color stays true, even after several months.

I use these two build little toy aquariums for my students as a reward. I charged them up before we use them by placing them on a windowsill for about 36 hours. While they did show some glowing properties, it was not really a strong glow. And some of the colors didn’t really glow at all either. They’re cute, and a decent quality, but I was disappointed in the glow in the dark effect.

I like the variety of colors of these stones , they are different, however they do not glow. But they are decorative. Cool

These things are so bright! I put them in a plaster stepping stone... it sat out in the sun all day and holy buckets! They light up like crazy! Definitely would recommend

Stones do not glow in the dark after being exposed to full day of direct sunlight

Using these rocks in a kids water table. Great colors and they really glow at night.
