Willow Breast Pump Sizing Insert | 19mm for 15mm-17mm Nipple Size | Improve Fit for Willow Wearable Breast Pump Flanges & Containers 24mm Only

Q: Can I use these for the zomee z2?

I don’t own the zomee but I have tried these with several different pumps and these inserts can pretty much fit universally into any 24mm flange.

Q: I measured for a 17mm flange. According to the sizing chart I would order a 19mm. Is that correct?

That is what I did and ir fit very well. I can use them in my willow go and my momcozy s12 pro!
