Please select the appropriate size flange insert for your nipple. If you are unsure which size is best, we recommend purchasing our Flange Inserts 13/15/17/19/21mm 10-piece set, which is suitable for most nipple sizes under 24mm and includes two that can be used simultaneously. The JIMOWANG Flange Inserts 15/17mm 8pc contains two of each size (4 sizes in total), and at least four flange inserts can be used simultaneously for work.

These flange inserts are compatible with Momcozy S12 Pro/M5/S9 Pro/S12/S9 Hands-Free breast pumps. They will reduce the 24mm shield nipple tunnel down to the correct size, but they are not suitable for 27mm shields/flanges or other sizes.

The size of your flange insert is crucial for both comfort and efficient pumping. Some moms may experience nipple swelling while pumping, so it's important to monitor the appearance of the nipple during pumping. It is recommended to replace the flange insert every 1 to 2 months. Please ensure you choose the correct size.

These flange inserts are BPA-free and made of food-grade silicone, making them easy to clean.
