afontoto 17mm Flange Inserts for 24mm Wearable Pumps — Silicone Sizing Kit for Momcozy M5/M9, Spectra, Medela, eufy, TSRETE

Comfortable fit for a range of breast shield sizes

afontoto presents a silicone sizing kit designed to fit most 24mm wearable pump shields. Developed with feedback from thousands of new mothers, this set includes 15mm, 17mm, 19mm, and 21mm inserts to adapt as your breastfeeding journey evolves. The goal is to help you find a comfortable fit and support more efficient pumping sessions without unnecessary expenses.

Thoughtful materials and safe cleaning

Crafted from food-grade liquid silicone, the inserts are soft and flexible for gentle skin contact. The design aims to enhance comfort during pumping and maintain a clean, hygienic setup. They are safe to sanitize with steam or boiling water and are dishwasher-safe for easy maintenance.

Right size, right time

A nipple measurement card helps you track size changes over time. When needed, swap to the most suitable flange size to help preserve comfort and pumping efficiency. In the middle to late breastfeeding stages, consider replacing sizes every 2-3 months to maintain optimal functionality.

Upgraded tunnel for smoother flow

The kit features a 12mm tunnel upgrade designed to facilitate milk transfer and reduce friction inside the flange. Some users report less friction and a more comfortable pumping experience during longer sessions.

These inserts are designed to work with 24mm shields and are compatible with Momcozy M5/M9/V1 Pro, Spectra, Medela, eufy, and TSRETE wearable pumps. The set helps you adapt a single shield to a range of sizes and brands.
