Our great 16 oz. (500 ml) Natural (HDPE) Wide Mouth Oblong Bottles offer the conveniences of a wider opening and space saving design. These remarkable bottles are great for storing larger items that are difficult to fit through other bottles, such as beans, vitamins and thick liquids. They are ideal for high-speed filling, and the often rough handling of interstate shipping. Bottles are flame treated, which makes label application easier. Includes a white (PP) cap with foam liner.
