The night is bursting with light when you wear Shutter Glasses (also known as Stunna Shades)! They're fun and the perfect flashy accessory to every outfit. The glasses feature shutter across the eye area that add to the fun look but don't really interfere with your vision. These Glasses are made to fit most adult heads but fit children as well. 3 modes: fast flashing, slow flashing, and steady on. The Glasses use 3 replaceable AG13 batteries (included).
