Maymom Flange Inserts 21mm Long – 2pc Pack | Fits Medela, Spectra, Willow, Momcozy 24mm

Customize your pumping fit with Maymom Flange Inserts 21mm (Long)

Maymom Flange Inserts 21mm (Long) are crafted from BPA‑free silicone to help you tailor the fit of popular 24mm and 25mm cups. Designed for comfort and versatility, these inserts slide into compatible flanges to create a snug, more personalized pumping experience without changing your routine.

Each package includes two inserts, making it easy to rotate between sessions or keep a spare on hand. The silicone surface feels smooth and gentle, contributing to a steadier seal during pumping while you focus on comfort rather than fit.
