A well-fitting inner shell is essential for comfortable and efficient pumping. Choosing the right size ensures smooth pumping. It's important to know that the size of the inner shell depends on the nipple diameter, not the size of the breast.
Measuring your nipple is very simple. Using a tape measure or ruler, measure the diameter of your nipple at the base, excluding the areola. Read the measurement in millimeters (mm).
Select the appropriate breast shell based on the size:
Nipple diameter 13-15 mm insert shield 17 mm
Nipple diameter 15-17 mm insert shield 19 mm
Nipple diameter 17-19 mm insert shield 21 mm
Nipple diameter 20-22 mm inner shell 24 mm
The other breast may require a different size. Therefore, measure the nipples of both breasts.
