Flange Sizing Kit 3 in 1 Ultimate with 10PCS Flange Inserts 13/15/17/19/21mm, Nipple Ruler, Cleaning Brush, Silicone Flanges Insert Kit for 24mm Most Pumps, Pumping Breastfeeding Essentials

Loved my kit! Came with two of each size, which was super helpful! Sizer was easy to use, and included sponge brush has been an instant favorite, ended up keeping it with my travel pump and a bottle of soap. Fits my spectra and my Medela, easy to install and remove.

This saved me and the beginning of my pumping journey when I recently gave birth!!Without this I probably would have considered giving up in the hospital because I needed a different size than what they offered and it was incredibly uncomfortable pumping originally. This also is amazing because it comes with so many different sizes that you will have access to if your sizes change or you have different sizes on each side.If you’re on the fence but it and you won’t regret it because even with the flanges that come with my pump from my insurance I use these inserts and they work with basically pump- also they’re silicone and softer than the plastic on the flanges.

These are great! I thought pumping was going to be the easy part of nursing... but there is a lot I didn't know, and having the right flang size is SOOOO IMPORTANT! I liked that this kit came with the measurement as well as so many options for flanges (even though you really only need the size you are) - it saved me time (and money) ordering it all separate and made pumping so much more comfortable. Putting a little coconut oil on the pump/flang also helps a ton to make the process more comfortable.

This fits flange size 27 not 24 like description says. Other wise it works fine.

This was a great and easy quick fix for my pumping problem. I run as a size 19 flange and most pumps don’t come in that size so it was causing me some irritation when pumping. I was recommended these flange inserts by my lactation consultant and they worked perfectly. Easy to install on any pump, we have 3 different brands on of pumps (mom cozy, spectra, and Elvie) and it fit all of them. They are silicone, easy to clean. Definitely would recommend to other moms struggling with proper flange sizes.

My breast pumps were just not working out! We got these found the right size and it was a game changer. Made pumping so much better

I bought because I liked that it would be compatible for my multiple pumps, but they do not actually fit into the Medela Harmony hand pump despite the picture of the compatible shield having that included. It does fit nicely into the Momcozy. Have not tried fitting into spectra shields yet.

Works perfectly with my breast pump
