Using your Baby Groot 3D deco light is a breeze. First, you'll need to buy 3 AA batteries and put them into the battery compartment. Then, find a nice spot on your wall and stick the crack - effect sticker. Hang the light on the sticker. It's important to note that the batteries aren't included. When the light starts to dim, replace the batteries. To keep it looking good, gently dust it with a soft cloth from time to time. Avoid getting it wet as it may damage the light. Enjoy having a piece of the Marvel universe in your home!
