Replace Your Large 24mm Shields: These Durceler flange inserts are designed to reduce your large 24mm breast shields to a perfect fit of 19mm. They are also compatible with 25mm Lansinoh and Freemie cups, making them the perfect solution for reducing your shield size.

Seamless Compatibility for Optimal Milk Expression: These inserts are suitable for nipple diameters between 16-18mm after a pumping session. Before pumping, ensure your nipple base circumference is 43.96-50.24mm for optimal performance.

Perfect for Small-Nipple Mothers: Our inserts are a great solution for small-nippled mothers using large breast shields. Maintaining the proper nipple tunnel fit enhances both comfort and milk output.

Replacement Guidance: For optimal results, replace these inserts every 4-12 weeks, depending on the duration and frequency of each pumping session. They are durable, clear, and comfortable, made of BPA-free silicone.

Maintain Compatibility with Hands-Free Bra Cups: These inserts maintain compatibility with most hands-free bras. If you have cups with detachable 24/25mm shields, simply use these inserts to achieve a perfect fit. Ensure the insert is fully fitted into the shield by slightly squeezing during operation.
