These come in many different forms. Traditional forms and newer ones without the need to store kerosene in them. Merely soak the wick and install. The idea situation for setting these up would be outside. I am going to leave you a link to Tessie from Mobile Home Living at youtube. She is absolutely wonderful.
The above image is a copy of the ones I have. As usual, you can get these from Amazon along with wicks, and the kerosene.
