Using this Glowing House Set is a breeze. First, follow the easy step - by - step instructions to decorate and assemble the paper houses. Then, use the Bare Paint Pen to draw circuits on the houses and attach the components. As the light fades, your houses will start to glow. Remember, if you're under 12, get an adult to help you during assembly. Also, Bare Paint should never be used on your skin and since it's not waterproof, keep it away from water. There's no special maintenance needed for this set, just store it in a dry place when not in use. Have fun creating your own Voltage Village!
