Flange Insert 17/19/21mm 6PCS Compatible with Momcozy S12 Pro/S9 Pro/S12/S9/Medela/Spectra etc Wearable Breast Pump 24mm Flange/Shield, Reduce 24mm Tunnel Down to Correct Size

Comes with a silicone sizing guide which was easy to use and easy to clean. Comes with many different size flange inserts that are very comfortable. They are also silicone and easy to clean. Made pumping so much better!

This kit was so helpful for figuring out the correct flange size of each side. It let me try out different sizes without spending an arm and a leg on new flanges. Plus, that tiny foam brush is really good at cleaning fiddly pump parts

These fit great in my mom cozy s12 pro! I was thankful for the ruler so I knew I was getting the correct size! Super comfortable and easy to was with the sponge!

These work great, I have to use two different sizes and the sizer was very helpful during the beginning of my nursing journey!

They do what they are suppose to. I wanted an extra set to have so I didn’t have to wash and let my mom cozy ones dry. I do like my mom cozy ones that came with my wearable pump better, they have a soft finish to them if that makes sense where it’s easier to insert them into my pumps. It is not as sticky going in and they aren’t as comfortable. But they do a great job for the price!

These are okay but aren’t compatible with momcozy. They don’t fit snug in the flange

Easy to use and easy to find your size. I recommend this to any of the pumping mamas. It’s important to have these as sometimes your nipples can be different sizes for pumping.

I’m a first time mom and wanted to nurse. This was so helpful and so easy to use to measure myself. I liked that it came with small inserts as I needed the 13mm and 15mmThis is something I would definitely buy as a baby shower gift for a new mom.
