In my view, according to this article is flawed. I had bought him for Halloween for the kids. The children wore the rings formed into bracelets. It made a few rings, the liquid ran out. The children were then the stuff (which probably should not be poisonous ...) anywhere on the skin. In addition, the liquid was distributed over our bed. Today, my daughter wanted to use the glow sticks as an additional beacon in the darkness. When buckling her is the stuff directly injected into the eye: Suuuuuuuuuuper, she screamed and cried!
My conclusion: Never again !!!!
I now have all the remaining lights (about 200 !!!!!!!!!!) disposed of, these things are too dangerous for me and in my opinion not available.
