15mm Flange Insert Compatible with 24mm Flange/Shield of Breast Pumps, for Momcozy S9 Pro S10 S12 Pro Medela Spectra Elvie Stride TSRETE S18 S21 S23 Bellababy kmaier NCVI MomMed BIOBOO

These inserts are perfect to make your flanges fit foR YOU! They fit most brands of flange sizes so it’s a better option that having to buy your name brand flanges! I’ve used on my medela pump in style, momcozy, spectra, and elvie wearable pumps. Love these inserts.

I absolutely love this!! The material is perfect!

The media could not be loaded.  So grateful for these flange inserts! They work like a dream! I have small nips and this size was perfect and fit great in the flange of my Bella baby electric pump! Great price helps too!

They seem to run small

I use the 20mm flange insert with a Spectra S2 24mm flange. I wish the insert fit more snug into the pump. There is always breast milk in between the flange and the insert. While I wash the flanges, inserts and bottles in between every pump, I think the constant removal of the inserts will cause them to need to be replaced more often. Just my own opinion. Other than that I’m happy with the product, price and quantity they came in.

Ordered these to use with my Elvie pump, they work great to downsize the flange! Sadly I was sent 2 different sizes as a set!! Now I can only use 1 at a time.

Why....? We don't have one boob.. we have 2 boobs. Why would you only include one of each size. Having to use different sizes on my pump.

I bought these on a whim, hoping they would fit my Bellababy wearable pump. To my surprise, they do well. They aren't the snuggest fit, and they will fall out if you flip the pump's tunnel side toward the ground. For wearable pumps on a budget, this is a great combo.
