Navy SEAL glow sticks are used by the military for a wide variety of applications. Navy SEAL glowsticks are waterproof, do not use electricity and are disposable. A SEAL glow stick can be used as light sources and light markers during an emergency or as a means to mark a campsite. There is no danger of sparking. We carry Glo-Toob Glowsticks in many colors as well as offer emergency light sticks that come in convenient 10-packs and battery-powered glowsticks.
