Flange Sizing Kit Flange Insert 13/15/17/19/21mm 10PCS for 24mm Flange/Shield of Most Pump, Reduce 24mm Tunnel Down to Other Size (10PCS 13/15/17/19/21mm for 24 mm Shields)

Love these flanges I didn’t know my size and was in the pit of postpartum and worried if my baby was getting enough. This helped my pumping experience by 1000%!!! I started getting more milk and my nip**es didn’t hurt anymore! It comes with the sizing kit and tells you what size to use based on how you measured. So that was also super helpful!

Great size variations. Need to re order since you can never have too many between all of your rotating pumps

Yes!!!!!!! Thank youuuuuuu

Super nice & easy for me to measure my size! Thanks!

It was super easy to find my correct size and use it with the Spectea S2.However, because the silicone is not see-through, I had a hard time making sure I was centered when using the pump. I ended up going with a different product altogether to use my pump more effectively.

Exactly what I needed, I’ve seen other products almost exactly the same and almost 5x more expensive so I chose this one, and have no regrets. Fit with my spectra flanges, and have increased my success with pumping.

this is definitely a must have item for new moms , many different sizes to try and the chart was very helpful! the product is very comfortable as well

Perfect because they fit right in my pump and made it the size that I actually needed.
