Nursi Luna Flange Sizing Kit 3 in 1 – 10 Silicone Inserts (13–21mm) Fits 24mm Shields | Pumping Essentials

Designed for comfort, built for daily use

The Nursi Luna Flange Sizing Kit 3 in 1 is crafted with input from an IBCLC to help new moms approach pumping with measured options. Instead of second-guessing, you’ll have a set of precise insert sizes ready to try, aiming for a comfortable seal and a steady pumping rhythm that fits your evolving needs.

Breastfeeding and pumping can be dynamic—nipple size and how a seal feels can change across days and weeks. This kit responds to that reality with a practical sizing approach and a simple method to verify fit, so you can focus more on the moment and less on the gear. The kit is designed to pair with standard 24 mm shields, broadening compatibility while keeping the setup straightforward.

Safe, practical materials matter. The inserts are made from food-grade silicone, BPA-free, and are easy to clean. A sponge cleaning brush is included to support quick maintenance between sessions. If you use the inserts regularly, you’ll find the recommendation to replace them every two months helps maintain performance and fit over time.
