Nursi Luna Flange Sizing Kit with Silicone Inserts (13/15/17/19/21mm) for 24mm Shields

Find Your Perfect Fit with Confidence

The Nursi Luna Flange Sizing Kit is crafted with guidance from an IBCLC to remove the guesswork from pumping. With five sizes and soft silicone inserts, you can tailor the fit to changing needs, aiming for smoother suction, more comfortable sessions, and a more efficient expression process.

What You Might Gain

Results vary by individual and pump system. The kit includes a claim of up to 30% increased milk flow when used with compatible devices, reflecting smoother flow and improved drainage in some routines. This is presented as a potential improvement rather than a guaranteed outcome, depending on your unique pumping setup.

• Five sizes included (13, 15, 17, 19, 21 mm) across 10 silicone inserts, allowing quick swaps to find a best-fit during different sessions.
• Soft, food-grade silicone provides a gentle, snug grip that concentrates comfort during longer pumping sessions.
• Designed for 24 mm shield pumps to streamline compatibility checks; note that 27–28 mm shields are not supported.

How It Fits Into Real-Life Moments

Use the IBCLC-approved nipple ruler tool to track size changes across breastfeeding stages. Pair measurements with the matching flange inserts for a consistent feel that supports effective coverage and drainage during pumping.

• Adapt to postpartum changes and varying pumping routines with multiple size options.
• Silicone inserts are reusable and easy to clean, ideal for busy moms on the go.

Safety, Care, and Maintenance

All inserts are BPA-free and made from food-grade silicone, prioritizing a safe pumping accessory. For peak performance, rotate inserts and consider replacing every 1–2 months to maintain fit and suction quality.
