21mm and 24mm pairs
How to measure your nipple:
- Measure the diameter of your nipple in millimeters (mm). Do not include your areola.
- Add 4mm to your nipple measurement when selecting your breast shield size.
(Ex. Nipple measurement 20mm + allowance 4mm = breast shield size 24mm)
If you’re in between sizes, go up to the bigger size.
(Ex. 25mm, your breast shield size will be 27mm/28mm)
