Nuliie10PCS Flange Sizing Kit 13/15/17/19/21mm for 24mm Flange/Shield of Most Pumps, Silicone Flanges Insert for Momcozy/Spectra Electric Breast Pump, Breastfeeding Essential Pumping Kit for Moms

This Nuliie flange sizing kit was a game-changer for my pumping journey! I had no idea how important the right flange size was until I started experiencing discomfort and low output. This kit made it so easy to find my correct size and improve both comfort and milk flow instantly.The materials are soft, easy to clean, and compatible with my pump. I love that it comes with multiple sizes so I could test and find what truly worked for me. It’s also super convenient to carry around and store.If you’re a new mom or struggling with pumping pain or inefficiency, I highly recommend giving this kit a try. It made a huge difference for me!

I got this flange measurement set to use with my Medela pumps (which all fit 24mm), and I'm really happy with it. I wanted a variety of insert sizes in case my needs changed, and this set delivered. The inserts are definitely more comfortable than pumping without them, and I love that I can include them in my regular sterilization routine.The set came with a small foam brush (handy for cleaning), a measurement card with sizing holes, and a pair of inserts in different sizes. Everything feels well made, and it's a great value if you're trying to find your best fit.

The sizer is so easy to use. The flanges themselves are flexible and comfortable. Easy to put inside the pump and easy to take out and clean. They also hold up well in the sterilizer. Would definitely recommend this rather than paying a fortune for new pump parts!

Other reviews say they are hard to remove, which I didn't think I would experience using a 25mm flange. I have had some difficulty but once you figure out a good technique it's easy. Having all the sizes and measuring tool is amazing. Though if you don't use some kind of lubricant before use like a nipple cream it can be a bit uncomfortable. Overall theyve been an amazing product.

These do not fit the 24mm flange of the Elvie Stride, but they did for in the 25mm of my Ameda Mya Joy plus. I like that they are clear so I had a better sense of what was happening since I seem to need a new size.

I have a spectra S2 and the flanges fit perfectly! Easy to remove too for cleaning. The only caveat is make sure the flanges are wedged in tightly into the pump parts. Otherwise the milk gathers in between the flange and the pump. Overall, very happy with these flanges!

This kit was perfect to size yourself at home and included multiple inserts to use once you found your size. All the inserts have fit with my spectra, medela hand pump, and the Ardo Melia wearable. Although I used the included sizer I also played with 2 different inserts to see which was more comfortable so It was nice it came with multiple sizes.

Pumping moms you need these. One they are so comfortable and aren’t hard like some flanges I have tried and it comes with multiple different sizes which is amazing because my nipples we’re always 2 different sizes! I would recommend these to every mom!
