4pcs 21mm Flange Inserts for Momcozy S12 Pro/S9 Pro/M5 Breastpumps

Content: The JIMOWANG flange insert set includes four 21mm inserts, which are designed to reduce a 24mm shield nipple tunnel down to a 21mm size (not suitable for 27mm shields). It is important to note that the size refers to the beginning of the tunnel, not the end. The size of your flange plays a crucial role in ensuring comfort and efficiency during pumping sessions. Be sure to monitor how your nipples appear during pumping to ensure they are not rubbing or feeling compressed inside the flange tunnel.
