The Bobino Bag Light is designed to clip inside your Bag or Purse and turns on easily with the roll of your finger across the switch. The bright LED light will illuminate your bag, a dimly lit menu, or a dark sidewalk and is always there when you need it. The included 2032 batteries last upwards of 12 hours and are easily replaceable by unscrewing 2 screws on the back. It’s Bobino…It’s Better!
