12 Colors Glow in the Dark Stones - SCUAN 100 Pcs Decorative Stones,Garden Pebbles Rocks for Outdoor, Artificial Decorative Stones Rocks for Walkway, Window, Yard Grass, and Fish Tank Decoration

I left it in sunlight for 6 hours and it shined as in picture below.I would give 4.5 star if there is such choice. The piece is made of light-weight instead of heavy glass but looks cute though.

They glow but they are not great for fish tank it says 100 per pack but they are small . I have a 55 gal fish tank and was hoping 3 packs would cover at least the bottom of tank but three packs didn’t even cover a corner.

These glow stones came highly recommended . Disappointing product. Less than 20% of the entire stones glow in the aquarium

I thought they were a lot larger than displayed but they are not, would recommend getting several bags if using for larger tanks.

These rocks are so much fun! They have a beautiful turquoise color during the day and at night they do exactly what they are supposed to do-they glow! Overall they are really fun and add more to our backyard during the day and at night. We had a BBQ last night and all our friends and family commented on them! My kids love them too and one of my nephew a actually put some in his room to match his glow in the dark stickers! Tou won't be disappointed with these at all!

No glow, nothing, sat out in bright sun for days and days

These glow-in-the-dark pebbles are awesome I put them in flower vases and he looks wonderful. And night the blue stones look kind of magical LOL. I love that they give you hundred pieces for such a low price I was going to use them for my outside path but I was afraid little kids my walk by and take him. I plan to use these for Halloween as a decoration later on with black light.

These stones are very interesting, my kid really likes to play with them, they kept him busy for days!
