The listing, Glow In There Dark Orbeez, Water Balls, Polymer Balls has ended.
These are great to have no matter what you need them for. I had about 10,000 that I took and put in a big bucket of water for a few hours so that they could grow. I gave them to my nieces and nephews and they were in my back yard, throwing them at each other. Needless to say, they were everywhere. But that night, after the sun was on them all day, they were glowing in the grass and for the life of me, I don't know why it was so mesmerizing. I was in aww just staring at the lawn glowing. Lol There's a few hundred in this bag. So have fun with them.
