MayMom Flange Insert Pure Silicone New and unopened 17 mm pure silicone

Key points about flange inserts: Custom fit: By inserting a smaller diameter piece inside the standard flange, you can adjust the tunnel size to better match your nipple size, preventing unnecessary friction and pain. Improved suction: A better fit with the right size insert can create a more efficient vacuum seal, leading to better milk extraction. Reduced nipple irritation: When a flange is too large, it can pinch or rub against the areola, causing discomfort; inserts can help alleviate this issue. Flexibility for different breast sizes: Some inserts come in various sizes and materials, allowing you to find the best option for your specific needs. 17 mm inserts x 2, made by Maymom.
