The Difrax Unscrewable base Natural for the S-bottle, together with the valve, ensures a constant flow of formula in the baby bottle. This prevents colic.
Suitable for the 170 ml and 250 ml S-bottle. The unscrewable base allows you to clean the bottle thoroughly and makes it easy to fill with breast milk ice cubes. The base is supplied as standard in the neutral colour white as shown in the image.
