Green "crackle" Glazed Buddha Oil Burner. These burners may be more suited to wax melts than water as the reservoir is fairly small (in comparison to the owl oil burners). You can absolutely use water and your favourite essential oils but just be aware that you will need to keep an eye on it and top up the water more frequently. Place a tealight in the back to warm your chosen aroma. Place on a dish or heatproof mat to protect surfaces and never leave unattended when lit.
