Find the Right Size for You
When it comes to comfortable, efficient pumping, a good fit makes all the difference.
Measurement Steps
1. Use a ruler or tape to measure the nipple diameter (mm) at the base of the nipple and choose a suitable cover.
2. Determine the size of a flange based on the measurement results.
Example
If the measured nipple diameter is 22 mm, it is recommended to use a 24 mm flange.
Judgment Method
Too Small
If the size is too small, it may not be able to suck out.
Suitable
The nipple is centered and can move freely.
Too Large
Excessive size may cause milk leakage.
