Himalayan salt lights give off a warm, reddish-pink glow. It is said they can improve your mood, improve sleep, ease breathing problems and allergies, and clean the air, among other benefits. And they’re beautiful! These lights are battery operated (batteries not included) so you can take them with you anywhere. If you use them outside, don’t let them get wet, and don’t leave them outside for too long! Each string is 108″ long and has 12 lights.
