Elsa fans are going to love this beaded light-up bracelet for a fun accessory to wear with any outfit. Bracelet lights up around Elsa's face with a rainbow of blinking lights (just press a button to the left of her). Batteries included, however it's always better to replace with new soon after you purchase, and this is only my personal opinion. Takes 2 button batteries(like you put in a watch) 3.0v CR927.
