This little round oil candle has several glaze colors swirled artfully. Matte green contrasts with glossy tans and blues. It has a fiberglass wick held by a clay bead. The wick will last indefinitely... the wick doesn't burn up, it just turns black at the top. Just fill about halfway up with non-smoking lamp oil. Adjust the amount of wick sticking out of the bead to adjust the size of the flame. Instructions for use come with it.
