Review on Portable Glow-In-The-Dark Square Luminous Silicone Ashtray - Funny And Cool Design - Pack Of 3, 8X8Cm by James Hova

Loved the glow to these. Very fun. Im sure it would be great with black lights too. We have used them very much and the color has become dirty. I'm not sure that it has any glow left and the cleaning doesnt get it back to being white. Its grimey a bit. Still the thickness has been good. Nothings burned through. It just gets dingy. I may just need to try soaking them in bleach water with good dish washing liquid. Still a great buy and maybe good to use just occasionally for special get togethers or parties or out of the pack use one for daily use and the others less often for other times to keep them glowing and clean.
