## Description

Nuliie 12PCS Flange Sizing Kit 16/18/20mm for 24mm Flange/Shield of Most Pumps, Silicone Flanges Insert for Momcozy/Spectra Electric Breast Pumps, Pumping Essential Kit for Moms

## Features

- [HIGH COMPATIBILITY] Nuliie flange sizing kit 16/18/20mm (12pcs) fit most 24mm wearable breast pumps. It will reduce the 24mm shield nipple tunnel down to correct size. Note: Not compatible with 27-28mm shields.
- [MUST-HAVE ACCESSORY FOR BREAST PUMPS] Achieve enhanced breast pumping, reduce pumping time, and maximize milk production by using the essential flange inserts for your breast pump. The comfortable and soft silicone material is designed to stimulate milk flow and increase comfort during use. With the added benefits of reduced pain and increased milk output, our breast pump flange inserts are a must-have for any breastfeeding mother needing to pump milk.
- [SAFE & EASY TO CLEAN] Ensure safety and maximize the performance of your breast pump with our flange inserts. Made from food-grade liquid silicone and free from BPA, these inserts are easy to clean and dishwasher safe. We recommend washing the pump inserts promptly after each use and replacing them every 2 months to maintain optimal functionality. Plus, receive a complimentary cleaning brush for added convenience.
- [CARING SERVICE] With our silicone flange inserts, you receive a free nipple measurement card to help you choose the perfect size. Compare the size of your nipple before and after pumping to ensure the most comfortable and effective fit. We provide unparalleled after-sale for mothers by answering your questions anytime and anywhere.
- [FRIENDLY REMINDER] Nipple size can vary throughout different breastfeeding stages, requiring different sizes of flange inserts for your breast pump. If you're aware of your exact nipple size, we recommend purchasing the corresponding size directly. However, if you're unsure, we suggest starting with our 10-pack of Flange Inserts, which contains five different sizes to ensure you find the perfect fit.
- Your order may come with either the new or old packaging, shipped randomly. Rest assured, both versions guarantee the same high-quality product inside.
