Cowbell is a quality brand of stainless steel dairy equipment. Transport milk from the vat to the kitchen. These billies are well made with a wide neck for easy cleaning and a rounded base. Supplied complete with flush-top lid. Metal milk billies expand and contract with temperature changes. If the lid becomes stuck, lay the billy on its side and pour hot water over the outer collar.
