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

The product itself is of good quality. However I am disappointed to be missing 1x 17mm flange. My order was delivered incorrectly with 3x 19mm flanges and 1x 17mm.
