Review on KarberDark Glowstick Set - 609 Pcs in Total, 240 Bulk Glow Sticks in 7 Colours with Connectors for Caps, Bracelets, Necklaces, Balls, Eyeglasses, and More - Light Up Toy Stick for Kid Party Birthdays - Glow in The Dark Stick by Erica Pratt

They disappear in an hour or less. After that, of course, they glow forever, but it would be better if they glowed very brightly for a shorter time. a box of glow sticks because I wasn't satisfied. However, this photo is less than an hour after I broke my first glow stick. As you can see, the glowstick that recently broke is significantly brighter than the one that broke fifty minutes earlier. I broke down because our last glowing party was so boring it could have been ruined two days earlier! The extra box they sent was a huge waste of plastic and resources. They were absolutely TERRIBLE!
