Using this Spiderman hand 3D wall - mounted deco light is super easy. First, find a nice spot on the wall where you want to place it. Then, if you want, stick the 3D crack sticker on the wall to create the cool effect of the fist breaking through. Next, open the battery compartment and insert 3 AA batteries (not included). Once the batteries are in, you can use the easy on/off switch to turn the light on or off. When not in use, it's best to remove the batteries to avoid potential damage. To clean it, just use a soft, dry cloth. And remember, this light is made of plastic, so don't drop it or use it roughly as it could break.
