Nursi Luna Flange Sizing Kit for 24mm Breast Pumps, 10PCS | 13/15/17/19/21mm Flange Inserts, Nipple Measurement Tool, Fit Electric & Manual Pumps, Soft Silicone, Comfortable Pumping : desertcart.co.uk: Baby Products

## Features

- 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. The right size and soft material help improve fit, reduce discomfort caused by rubbing or squeezing, and support a more comfortable, smoother pumping experience with improved efficiency for daily pumping moms.
- Easier Sizing Guidance: Developed by an IBCLC, this 3-in-1 nipple flange sizing kit includes a nipple measuring ruler and detailed instruction manual to help moms measure correctly and choose the right flange insert size. We recommend comparing nipple size before and after pumping for a better fit. Flange size may change over time, making multiple insert sizes helpful as your pumping needs change for a more comfortable, efficient pumping experience.
- Easy Care & Reusable: Reusable and easy to clean, these silicone flange inserts are dishwasher safe for everyday convenience. A sponge cleaning brush is included to help simplify cleaning after use. We recommend replacing the inserts every 2 months to help maintain optimal suction performance and a consistent fit.
