Better Sizing For Better Pumping: Nursi Luna Flange Sizing Kit 3-In-1 is developed by an IBCLC (International Board Certified Lactation Consultant) to help moms find the right flange size more easily. It helps reduce the confusion many moms face when standard breast pump flanges feel too large, uncomfortable, or not quite right, supporting a more comfortable pumping experience and improved pumping efficiency from the start. Highly Compatible: This 10PCS flange sizing kit includes 5 sizes to choose from-13/15/17/19/21mm soft silicone flange inserts (2 of each size)-and fits most 24mm electric breast pump and manual breast pump flanges/shields. It helps size down the 24mm shield nipple tunnel for a better fit and more comfortable pumping. Note: Not compatible with 27-28mm shields. Softer, More Comfortable Pumping: Made of BPA-free food-grade liquid silicone, these flange inserts feel softer and gentler than hard plastic flanges during daily pumping.

We recommend comparing nipple size before and after pumping for a better fit.
