Nursi Luna Flange Sizing Kit with Silicone Inserts – 10-Piece, Nipple Ruler, 13–21 mm for 24 mm Shield

Meet the Nursi Luna Flange Sizing Kit, a thoughtful companion for your pumping routine. This 10-piece set brings together five silicone flange inserts in 13, 15, 17, 19, and 21 mm, plus a nipple ruler and a cleaning brush. Designed for busy moms, the kit travels easily and adapts to changing needs without guesswork, helping you personalize your fit with confidence.

Designed for comfort, built for daily use

All inserts are crafted from BPA-free, food-grade silicone. The soft, cushioned surface is gentle on sensitive skin, while the range of sizes gives you room to adjust as days go by. A well-matched size can support a steady pumping rhythm and reduce rubbing, making sessions feel more natural and comfortable.

• Five size options: 13 mm, 15 mm, 17 mm, 19 mm, 21 mm
• Compatibility with a 24 mm shield
• Includes a nipple measurement ruler for accurate sizing
• BPA-free silicone, easy to clean and maintain
• Sponge brush included for simple sanitation

How to measure and choose your fit

Use the nipple ruler to compare your measurement with the inserts. Start with a mid-range size and adjust for comfort during a short pumping session. Once you find a comfortable fit, you can keep using it to maintain consistency.

• Step 1: Measure with the ruler
• Step 2: Try inserts during a quick session for comfort
• Step 3: Sanitize after use by boiling or cleaning with soap

Care and maintenance

Rinse and wash with mild soap, then air dry. The silicone is boil-safe for sanitation, and the included sponge brush helps with deeper cleaning. This keeps your kit durable and ready for daily use.

Choosing Nursi Luna means selecting thoughtful, user-friendly gear designed to support your pumping routine with practical options and clear guidance. This sizing kit offers flexibility, comfort, and convenience for many moms during their breastfeeding journey.
