Nursi Luna Flange Sizing Kit – 10 Silicone Inserts (13–21mm) for 24mm Shields | Pumping Essentials

Meet the Nursi Luna Flange Sizing Kit

Designed by an IBCLC, the Nursi Luna Flange Sizing Kit takes the guesswork out of flange fitting. It includes 10 silicone inserts in sizes 13, 15, 17, 19, and 21mm, with two inserts per size, and is intended to pair with your 24mm shields. The kit aims to offer a comfortable, secure seal across pumping sessions, helping new and expectant moms feel more confident in their routine.

What’s inside

• Ten food-grade silicone flange inserts in sizes 13, 15, 17, 19, and 21mm (two per size).
• Designed for use with 24mm shields; note: not compatible with 27–28mm shields.
• BPA-free, soft silicone crafted for repeated use and easy cleaning.
• Includes sizing guidance to help you track changes and pair with the right insert for a snug seal.

Why this kit matters

Every pumping day can feel different. The right flange size can contribute to a comfortable seal and steady suction, which may reduce irritation during longer sessions and support a smoother pumping rhythm. This kit is built to adapt as you and your baby grow and your needs evolve.

• Soft, durable silicone supports comfortable wear and repeated use.
• Multiple sizes provide options for a precise fit as your sizing changes through nursing stages.
• Compatibility with 24mm shields helps you expand or refine your existing pumping setup.

How to use

• Use the IBCLC-tested nipple ruler to assess size changes over time.
• Test inserts with your 24mm shield to identify the most comfortable seal.
• Rotate inserts as needed and replace every 1–2 months for best performance.

Care and safety

Clean with mild soap and warm water, then air dry. Store away from heat. Regular replacement (every 1–2 months) supports ongoing performance and hygiene.

Ideal for new moms, those adapting to a breastfeeding routine, or anyone seeking a more comfortable, consistent pumping experience with a 24mm shield system.
