16 oz Blue E-Z Cap Glass bottle - (16 oz = 473.16 ml) includes FDA approved flip-tops and grommets (not assembled). E.Z.Cap bottles contain more glass than the average bottle out in the market. That means your bottles will last longer and can hold more pressure than any other bottle you will find. E.Z. Cap bottles are pressure tested and guaranteed to 100psi and this makes them perfect for high-carbonation brews, such as kombucha. These quality swing-top cap closure keep carbonation better than a crown top will – although, if you prefer a crown top, they're fitted for that too. Height: 10" Diameter: 2.75" . NOTE: Eight 16 oz bottles = 1 gallon
