Our Concrete Vessels are 100% Handmade, sustainable, and reusable. These vessels are NOT sealed and are NOT candle pour ready. If you wet/wash the vessel, please allow 2 days to dry before using. If used for Candles, each vessel holds 8.5oz of candle wax. These Vessels are great to use as Planters, Home Decor, crafts, etc. :) **you can seal these vessels with your sealer of choice** Please allow an additional 2-3 days of shipping as these are made upon ordering. IF USING FOR CANDLES, PLEASE TEST YOUR CANDLES! START WITH A SMALLER SIZE WICK FIRST TO ENSURE NO OVER-BURN OR CRACKING HAPPENS. MAX BURN TIME FOR CONCRETE CANDLE VESSELS ARE 3 HOURS, NO MORE THAN THAT :)
