Our Poppy vessel is our favorite! Filled with 7 to 8 ounces of coconut wax and a hemp wick. 
Please leave your candles lit for no longer than two hours at a time. And trim your wicks before each use basically almost all of the black should be gone each relight to ensure the cleanest burn and the integrity of the concrete vessel. Concrete candles can get hot so I recommend a coaster something underneath to protect your surface. 

please practice basic candle safety!
