Box contains instructions, 2 glass pillar-type vessels, and 2 floats. NO WICKS are included.

Un-Candles burn vegetable oil, which floats atop water.  The water can be colored if desired.  The float has pockets for air, so the flame burns very consistently.   Also, vegetable oil has a relatively low flash rate, making these a much safer candle.

When introduced, these were unlike anything on the market. So 70's.
