The classic for marking and signalling, in case of emergency, at parties or simply for camping and outdoor life. The glow stick works well under water and in worst conditions. It is always a highlight at night walks or at the camp to mark paths and obstacles. Glows first very brightly for about 1/2 hour, then about 3 hours with normal light and for the next 8 hours glows dimly. Always keep in a closed bag, dark and cool. Shelf life: unopened ca. one year.
