Using these light sticks is easy. Just bend the stick until you hear a cracking sound, then shake it gently to activate the glow. They're great for emergencies, Halloween parties, or camping trips. Keep them in a cool, dry place when not in use. Don't try to open or cut the light sticks as the liquid inside might be harmful. If the glow fades before you expect, it might be because the stick wasn't stored properly. Have fun using these light sticks in your adventures!
