ULTRA BRIGHT AND LONGER LASTING - Perfectly engineered under strict quality control, these glow sticks are made from high quality materials to ensure up to 3-4 hours of glowing light so you could enjoy your party without worrying they would fade away. QUALITY CONNECTORS THAT STAY PUT - Probably the most annoying thing is to start putting your glow sticks bracelets together only to find out that the connectors are so poorly made that they just keep popping. Unlike others, we've made sure to use only premium quality materials so your connectors stay put. SAFE FOR KIDS - You can be relaxed knowing your children are safe when playing with the glow sticks. Their sturdy design makes them harder to snap so they don't easily break and start leaking like inferior products on the market.
