Using this mason jar light is easy. First, insert the light string into the mason jar. Then, place the special paper around the jar to create the starlights effect. You'll need to provide your own batteries for the light string. When it comes to maintenance, keep the jar away from sharp objects to avoid scratches. You can clean it with a soft, damp cloth. Also, store it in a dry place when not in use. Remember, the batteries are not included, so be sure to have some on hand to enjoy the warm starlights.
