LOZAEVE 16mm Flange Inserts: Seamless Compatibility for Optimal Milk Expression

LOZAEVE 16mm flange inserts are designed to fit various breast pump shields, including Spectra S1/S2, Bellababy, Elvie, Paruu R12, P10, Momcozy S9/S10/S12/M1, Wearable, Freemie, Evenflo, and Maymom. These inserts reduce a 27-28mm nipple tunnel to a smaller, more comfortable 16mm. They are also compatible with Medela pumps such as PersonalFit Flex, Harmony, Freestyle, Swing Maxi, Sonata, and Symphony, cutting down the 27mm tunnel to 16mm. Each pack includes 2 pieces.

Seamless Compatibility for Optimal Milk Expression

These inserts are ideal for mothers with small nipples, ensuring a snug and comfortable fit during pumping. Suitable for nipple diameters of 13-15mm after a pumping session or a 34.54-40.82mm base circumference before pumping. Proper fit is essential for comfort and efficient milk production.

BPA-Free, Durable, and Comfortable

Crafted from high-quality silicone, these inserts are BPA-free, durable, and comfortable. They assist in more effective pumping and maximized milk expression, while helping to avoid nipple trauma or irritation.

Maintain Compatibility with Most Hands-Free Bras

These inserts maintain compatibility with most hands-free bras. You can use the original 27/28mm detachable shields with most hands-free bra cups by inserting these 16mm inserts. For the perfect fit, slightly squeeze the inserts during operation to ensure they fully conform to the shield.
