Flange Inserts Compatible with S12Pro S12 / S9 Wearable Breast Pump,Reduce 24mm Shield/Flange Nipple Tunnel Down to 17/19mm, 4pcs

I bought it for my momcozy pumps and it fits perfect i can barely tell they’re there

These fit perfectly in my momcozy pumps. What a huge difference. So much less pain. These are easy to remove for cleaning as well

I didn’t know that when you buy breast pumps it’s not a “one-size fits all” and having the correct flange really makes a difference. It was easy to use and insert in the momcozy

The 17mm fits perfectly, I've seen an increase in my milk supply since I started using it.

Save you pesos ladies and buy these ones! It comes with a four pack at half the price mom cozy charges 10$ for one single flange.

Love that this is compatible with both my Spectra S1 and Elvie pump phalanges

I have a few different pumps I use but they all come with big flanges so these are great to make them my size, They fit perfectly in lots of the flanges I have. They are easy to clean and sterilize and are pretty sturdy so will last a good while.

Granddaughter was having a bit of trouble nursing. She asked me to order these flange inserts. She used them and they did help tremendously. She is very pleased
