Medela 21mm 2xOne-Piece Breastshield

Measure Nipple Diameters Before Purchase

One size does not fit all when it comes to breast pumps. Taking careful measurements of your nipple diameter is essential to ensure a proper fit. We recommend printing out a triple ruler as shown in the photo and measuring your nipple diameters before making a purchase.

Product Features

Inclusive Kit: Your purchase includes 2 one-piece breastshields, 2 valves, and 4 membranes. These components are designed to work seamlessly with Medela’s range of pumps, including the Pump in Style, Lactina, Symphony, Swing, and Mini Electric models. However, the kit is not compatible with the FreeStyle, Swing Maxi, Sonata, Pump in Style with maxflow, or Harmony (manual pump).

Medical Compliance: This product is a US FDA registered medical device (No. D192499). It is inspected and compliant with both US FDA and EU standards for food contact containers and class II medical devices. You can view the test reports online for additional reassurance.

One-Piece Design: Contrary to some two-piece breastshields, this one-piece design ensures that the bottle connector and flange are integrated. This provides a more durable and seamless sealing mechanism. If you are a fan of the traditional two-piece design, please refer to ASIN B07WLZGYJP.

BPA and DEHP-Free Material: Made from BPA and DEHP-free materials, and all components are steam-safe for sterilization. The product comes retail poly-bag packed, sealed by the manufacturer, Maymom. Please note that these are not original Medela parts.
