Nursi Luna Flange Sizing Kit 3-in-1 — 10 Inserts (13/15/17/19/21mm) for 24mm Shields | Pumping Essentials

The Nursi Luna Flange Sizing Kit 3 in 1 is designed for new moms seeking flexible, comfortable pumping sessions. Developed by an IBCLC, this kit aims to reduce sizing guesswork and support a routine that feels right, without promising overnight results. The set focuses on comfort, fit, and ease of use, so you can approach pumping with more confidence.

Kit at a glance

• 10 silicone flange inserts across five sizes: 13, 15, 17, 19, and 21 mm (two inserts per size).
• Designed to fit with 24 mm shields/shields; note: not compatible with 27–28 mm shields.

Why size matters

Nipple size can shift during different feeding stages. The included sizing approach, guided by IBCLC recommendations, helps you explore sizes to find a snug, gentle seal that supports comfortable pumping sessions. Pairing the right insert with your existing shield may contribute to a calmer pumping experience.

Materials & care

• Made from food-grade silicone, BPA-free, easy to clean, and dishwasher safe.
• Includes a sponge cleaning brush for quick maintenance.
• Replace flange inserts every two months for best performance.

How to use and what you might notice

Pair the inserts with your existing 24 mm shield for a customizable fit. If you feel tugging or an overly tight seal, try a smaller size; if there’s slack, move up a size. Realistic expectations: comfort and efficiency may improve with the right fit.

Gift-ready and practical

This kit makes a thoughtful, practical gift for new moms seeking a smoother pumping routine and greater confidence in choosing the right size quickly.
