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 fromβ€”13/15/17/19/21mm soft silicone flange inserts (2 of each size)β€”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. Whether you need different sizes for each side or size changes over time, this 10PCS kit (13/15/17/19/21mm) offers flexible options for more comfortable, more efficient pumping. - Safe For Mom And Baby: Made of food-grade, BPA-free liquid silicone, these flange inserts are safe, reusable, easy to clean, and dishwasher safe. A sponge cleaning brush is included for added convenience. We recommend replacing inserts every 2 months to help maintain optimal suction.
