When you buy the BonFeu BonBiza you cannot do without this functional lid. The lid fits over the fire tray and cooking plate to provide complete protection when the BonBiza is not in use.
Although the BonBiza is made from beautiful (corten) steel and can therefore take a beating, it can be very nice to close the BonBiza with a lid after use. The fire will after all go out quicker due to the lack of oxygen. Moreover, rainwater will not have a chance.
