Was honestly perfect exactly what I needed. We didn’t wanna buy a full-size flanges so we went this route and it worked perfectly fits into their snuggly and helps produce a lot more milk.

THIS IS A MUST HAVE!! I took this with my to a lactation consultant absolutely loved it so much would say every breastfeeding mom that pumps needs this

This sizing kit is very practical and makes it much easier to figure out which flange size works best. I like that it includes several different sizes, so you can test the fit without having to purchase each size separately. The pieces are easy to use and convenient to keep with pumping supplies. Great value for the number of sizes included!

Recommend for nursing mothers great quality

I bought this Nursi Luna flange sizing kit for my daughter because she was having trouble finding the right fit with her 24mm pump flanges, and this set has made a noticeable difference for her. The kit includes multiple insert sizes and a measuring tool, which made it easy for her to figure out what she actually needed. Having all the sizes right in the box meant she didn’t have to guess or place extra orders — she could try each one and immediately see what felt most comfortable. The soft silicone material is gentle and flexible, which she prefers over the firmer plastic flanges that came with her pump. Once she found her correct size, pumping became much more comfortable, and she noticed better milk output. She also said the inserts helped reduce rubbing and pinching, which had been a problem before. The measuring card is straightforward to use, and it’s helpful to have on hand because nipple size can change over time. The inserts fit perfectly into her 24mm shields, and she’s used them with both her electric and manual pumps without any issues. Cleaning is simple too — the silicone washes well, and the little brush included in the kit makes it easy to keep everything clean. A thoughtful, practical kit that takes the confusion out of flange sizing and helps make pumping more comfortable and efficient for new moms.

YOU NEED THIS! I did a comparison of how quickly milk started coming out using the 19MM, 21MM, & the 24MM. The 24MM is what I was using for the past 2 months. The 19MM INSTANTLY started giving me more milk more efficiently than the 21MM & 24MM. I’m a 19MM & have been missing out on extra milk I’ve left in my ducts when pumping. 🤦🏽‍♀️

Love the size that comes with it, and the flanges easily fit the Medela Melody.

Good set of flanges for the price! They fit my spectra great!

These breast pump flanges have been good so far. They fit comfortably and make pumping easier. The sizing is helpful to make sure the flange is the right size

Fits standard 25mm lansinoh breast pump flange!!

Es súper variable y se adecuada a tu medida

After using the wrong flang size and wondering why pumping was causing pain this was a life saver. The measurements are spot on and the adjusters fitted right into my current pump. Huge difference in comfort and milk output.

Sizing tool is helpful and the flanges are working well and are comfortable.
