Perfectly engineered under strict quality control， these glow sticks are made from high quality materials to ensure up to 6 hours of glowing light so you could enjoy your party all night without worrying they would fade away.^ This pack was thoughtfully designed to provide the ultimate glow party experience. Whether you are into chicy bracelets or cool necklaces， our party kit gets you covered.^ We've designed our glow sticks so that you can be relaxed knowing your kid is safe when playing with them. Their sturdy design makes them harder to snap so they don't easily break and start leaking like similar products on the market.^ 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. ^
