Um, they are candles which fit the lanterns.
They are made of Bees Wax, so smell lush and provides a less smokey flame!
Apparently they last 12 hours or more, so that romantic night can last 'forever'!!
Fit the standard large candle holders.
What else can you say?
They light up, they smell nice, they last a long time .......... er ..... apparently if there's nothing left to eat, they are edible ....
