IVARONAL 10pcs Flange Insert Set — 13/15/17/19/21mm (2pcs each) for Breast Pumps

Introducing the IVARONAL 10pcs Flange Insert Set, a versatile upgrade designed to tailor shield size for a wide range of popular breast pumps. This set includes multiple sizes (13, 15, 17, 19, and 21 mm) with two inserts per size, plus a nipple measuring tool to help you identify the best fit. Compatible with brands such as Momcozy Air1/W1/M9/M6/M5/S12 Pro/V1 Pro/V2, Spectra, Medela, and Elvie, these inserts offer a flexible approach to comfortable pumping across different devices.

The inserts are made from soft, food-grade silicone that sits gently against the skin. The result is a snug, skin-friendly fit that can contribute to a smoother pumping rhythm during sessions. While individual experiences vary, users often appreciate reduced pressure around the nipple area and a more balanced fit when switching between sizes or pumps. This set is designed to complement your existing equipment, not to replace it, and aims to support a calmer, more confident pumping routine.

Care tips: Before first use, and between uses, sterilize by steam, boiling water, or microwave steam bags. After cleaning, rinse thoroughly and air dry. This approach helps keep the silicone supple and ready for comfortable pumping sessions.
