Product Description
How to measure to get your comfortable flange size:
Measure the diameter of your nipple- not the areola
If the diameter is between 13-14 mm before a pumping session and/or 18-20mm after a pumping session, then the 17mm Flange is the correct fit for you.
This is a guide for fitting that always works with your comfort.
