I honestly don't know what I was thinking when I ordered this product. We don't play frisbee at night. But I did experiment with the frisbee, just to see if it actually glowed in the dark....not too good. There was a very pale white, not green, glow....very pale. I guess I was expecting it to be a little brighter. The quality, otherwise, is great. I would not order another "Glow-in-the-Dark"
