Using these LED twig lights is a breeze. First, insert 3 AA batteries into the battery compartment (batteries are not included). Then, place the twig branches wherever you want to add a warm and inviting glow, such as on a table for a centerpiece or around the venue for a party. When it comes to maintenance, keep the branches away from water to prevent damage to the LEDs. If the lights start to dim, simply replace the batteries. These twig lights are designed for indoor use, so don't expose them to the elements. With proper care, they'll last you through many special occasions.
