Flange Inserts 21mm for 17mm-20mm Nipple Size, Fits Momcozy, Elvie, Willow and More Breastpumps

JIMOWANG Flange Insert 21mm *4: This product can reduce the 24mm shield nipple tunnel down to 21mm in size, but it is not suitable for 27mm shields. The size specified refers to the beginning of the tunnel, not the end. The size of your flange is crucial for comfort and efficiency during pumping. It is important to observe how your nipples look during a pumping session, as they should not rub or feel squeezed inside the flange tunnel.

Compatible Flanges: The JIMOWANG flange inserts are compatible with Momcozy S12 Pro/S9 Pro/S12/S9 Hands-Free breast pumps. They also fit 24mm breast shields for various brands, including kmaier, TSRETE, Medela, Spectra, Elvie, Willow, Bellaaby, MomMed, MISSAA, Motif Luna, Ameda MYA, Ainsir, Phanpy, Lulia, NaNaLazy, Luxlady, kidzio, eulumap, Teexin, Fisroa, KISSBOBO, Goldeep, BIOBOO, Mumeasy, Nanawawa, TOVVILD, and CPPSLEE.

Wide Application: These flange inserts can be used with most hands-free bras on the market. You can still use most hands-free bras, even with the inserts installed inside the 24mm detachable shields.

Safety Material: The JIMOWANG flange inserts are BPA-free and made of food-grade silicone, making them easy to clean.

Usage: The JIMOWANG 10-pack flange insert set contains two of each size (5 sizes in total), allowing you to find the correct size for your nipples. At least two flange inserts can be used simultaneously for work. If you are unsure which size is best, we recommend purchasing our Flange Inserts 13/15/17/19/21mm 10-piece set to find the perfect fit.
