Flange Insert 17mm, Compatible with NaNaLazy/TSRETE/Bellababy/Lansinoh/momcozy S9/S12/S9pro/S12pro,Wearable Breast Pump Shields/Flanges，Milk Collector 24mm Universal (17mm)

In the picture and the heading it says it's 4 pieces but in the description it says 3 pieces. That's quite a sneaky thing to do honestly. I will not be returning it however because I actually need the product but beware!

Read the description, because we bought it thinking we were getting 4 pcs and instead got 3 and when I read the description it said it was 3 pieces.

Life saver. Not the easiest to put in and out, but saved my nipples from a far too big flange. The pump companies need to let us choose out flanges that comes with our pump, like bra sizes. It’s not one size fits all!!!

I was transitioning from breastfeeding to pumping when my 7 month old started getting teeth and I was SO sore from pumping so much. My Lansinoh pump came with 25mm flanges and I didn’t realize that it was the wrong size until I googled why pumping was so painful. Anyway, I found these flange inserts and they have made a world of a difference for me. They fit perfectly in the 25mm flange and my nips are much less sore and swollen after a pumping session. 100% recommend! I will not pump without them now.

Something that’s so frustrating as a pumping mom is that even though most of us are size 17-19 our sizes aren’t included in the pumps kits. These fit so nicely and they are so comfortable and easy to wash!
