IVARONAL Flange Inserts – 10PCS (13mm & 15mm) for 24mm Shields, Compatible with Momcozy/Spectra/Medela

Find Your Perfect Fit for Confident Pumping

IVARONAL introduces a thoughtful 10-piece flange insert set designed to help you tailor the tunnel size of your 24mm shields. With five inserts each for 13mm and 15mm, this set gives you flexible sizing options without buying new shields. The aim is to provide a closer, more comfortable fit during pumping, which many users find improves the overall feel of sessions. While results can vary, choosing the right size can influence how secure and supported you feel while pumping.

How it helps in everyday pumping

When shields feel too large or too tight, it can lead to rubbing, discomfort, or pressure spots. These inserts slide into place to reduce the 24mm tunnel to a more snug diameter, offering a smoother, more controlled experience. You can swap sizes as needed during the day or across sessions to accommodate changes in nipple swelling, milk flow, or shield type.

• Two sizes included: 13mm and 15mm, five inserts per size.
• Made from food-grade silicone, BPA-free, skin-friendly and odorless.
• Snug fit helps minimize gaps and rubbing, potentially enhancing comfort during longer pumping sessions.
• Easy one-step installation and removal for quick size changes between pumping rounds.

Compatibility and safe care

These inserts are designed to work with many popular pumps that use 24mm shields, including Momcozy, Spectra, Medela, and other major brands. Note that they are intended for 24mm shields and may not fit 27mm systems. For best results, inspect inserts for deformation or yellowing over time and replace as needed.

• Easy to clean after use with warm soap and water; can be sanitized by steam or boiling methods.
• Lightweight and flexible silicone cushions the fit without adding bulk to your setup.
• Durable, soft-touch material designed for repeated daily use across sessions.

In practice, the inserts offer a practical option for moms seeking a tailored fit without purchasing new shields. They present a practical, non-prescriptive path to potentially more comfortable sessions, with the understanding that experiences vary by individual and pump model.
