Glow Stones

Premium Glow Stones are 40%-60% brighter and offer longer glow performance than other glow-in-the-dark stones commonly found on the internet.  The applications are endless for the Glow Stones, and unlike others, they are not a resin but a photoluminescent aggregate that absorbs UV light to glow in the dark for 6-8 hours. This makes them more durable and they are also non-toxic and swimming pool chemical friendly.  Made in Michigan
