I used these sto help myself and other moms i work with learn proper fitting for flanges while pumping that variety helped show the difference in sizes for each person and the importance of finding the right fit

If your pump automatically comes with a 24 mm flange than these are great. I use them everyday and they're easy to clean soft silicone. They don't fall out and can be easily stored with the rest of your pumping supplies

I like that it came in a 3 pack with different sizes as the correct size is so important for milk production

Works as intended

These flanges fit in my Medela hand pump and my wearables. They have been very helpful.

Perfect! Took my pumps from a standard 24mm to the 19 I need. I love that the is set comes with multiple sizes. Perfect for someone who is testing out their best fit.

I needed options and this worked great. I hate pumping so I needed something to adjust and make it easier.

Just make sure that you have the 24 size shield and they will fit in there. Snug

So far so good. Fit my philip avent manual pump and my evenflo electrical pump!

Haven’t used it yet, but looks nearly identical to momcozy flanges. Nice tight fit. Silicon is slightly thicker than momcozy ones. This set is perfect if you buy the momcozy pump and need smaller size flange.
