Nuliie 10Pcs Silicone Flange Inserts – Sizes 12/14/16/18/20mm for 24mm Shields

Tailored comfort for your pumping sessions

Meet the Nuliie flange sizing kit — a 10-piece silicone collection that helps you dial in the shield size you need. The set centers on common 24mm wearable pumps and offers sizes 12, 14, 16, 18, and 20mm. This helps you customize the fit, reduce tunnel pressure, and seat your nipple more comfortably inside the shield, creating a calmer pumping experience.

What you get

• 10 silicone inserts in five sizes (12/14/16/18/20mm) designed to fit most 24mm shields
• Complimentary nipple measurement ruler to compare size before and after pumping
• Free cleaning brush for quick upkeep
• Dishwasher-safe, BPA-free, food-grade silicone for easy care

How it works in real life

Imagine a late-night pumping session after baby settles down. The inserts slide into your shield with a softer edge, reducing friction and helping you feel more comfortable during use. With the right size, you may notice smoother flow and less discomfort over time, which could translate to shorter pumping sessions for some users.

On busy mornings, you can swap in a different size to accommodate shifts in nipple shape or stage. The kit’s five sizes cover the common range many moms need, letting you explore which feel works best without purchasing single sizes upfront.

Care, safety, and ongoing support

• Made from food-grade silicone that is BPA-free and dishwasher-safe
• Prompt cleaning after each use helps maintain performance; replace inserts ~every 2 months
• Includes a free nipple ruler and responsive after-sales support for sizing questions

Notes and reminders

Flange size needs can change during different pumping stages. If you know your exact size, start there. If you’re unsure, the 10-pack provides varied sizes to help you find a comfortable match.
