- Compatible with Most Breast Pumps: LOTBILL flange insert is suitable for most wearable breast pumps and 24mm breast pump flanges/shields(not for 27mm and 28mm shield), such as it is compatible with Momcozy S12 Pro/S9 Pro/S12/S9/S10/Medela/Spectra/Willow/Elvie and other. Simply insert the right size – works great with breast pumps to reduce discomfort and improve suction
- The Importance of Choosing the Right Size: According to professional lactation consultants, a mother's nipple size may vary throughout the breastfeeding process. To save moms time and energy in finding the correct size, we offer an accurate and useful nipple measuring tool. Say goodbye to the pain and inefficient pumping caused by incorrect sizes
- Care for Moms and Babies: Our flange sizing kit is made from food-grade silicone materials, free from BPA. They provide a soft texture that is gentle on delicate skin. The flange inserts fit closely with your skin, promoting efficient milk expression without any foreign body sensation. Additionally, they are reusable and suitable for taking care of the health and safety of mothers and children
- Easy to Clean and Care: Comes with a handy cleaning brush for quick hand washing, and the inserts are top‑rack dishwasher safe. And ready for your next pumping. After each use, the replacement breast pump parts can be washed with mild soapy water, then rinsed with clean water. To maintain optimal function, we recommend replacing the pump accessories every 2 months
- Enhanced Pumping Experience: A proper fit means less friction, less pain, and more milk. Moms report shorter pumping sessions, fewer sore spots, and a more productive session every time. No more guessing your size! The included ruler helps you measure accurately for a truly Comfortable pumping experience
