Each dripless oil dispenser is hand shaped on a pottery wheel and signed by the artist in Spain. From base to top of pour spout, the oil decanter measures approximately 4″ wide by 7″ high. It does not open so the way to fill it or wash it is by filling from the hole along the rim. All our ceramics are lead free and food safe. The best way to wash the dispenser is to fill with hot soapy water and to then rinse several times. Not for use in microwave.
