These are handy little flash lights. Run on AAA batteries ( not included) I haven 1 on my purse so i can quick access it. Gave 1 to my daughter too. There is also one hanging by the door in case the power goes out. Small and bright. Perfect for anything. #Ranboosterreview #Sponsored #SSZY https://www.amazon.com/SSZY-Flashlight-Aluminum-Lanyard-Included/dp/B07BGTK9J7
