Safe, comfortable material and rounded design protect delicate skin while measuring. Durable and easy to clean for repeated use during the postpartum period.

How it works (simple steps) Align the zero mark on one side of the nipple and read the measurement directly; you can view in real time or take a photo for reference. Or try the smallest hole first: insert the nipple into the hole to check fit; it should sit comfortably in the opening. Use the measurement to select the matching breast flange or shield size.

After delivery: Verify flange size as nipple size can change in the early weeks of breastfeeding. When switching pumps or shields: Compare measurements to choose compatible flange sizes for different pump brands.
