    This kit has everything you need to find your correct sizing. Definitely recommend even if the hospital sizes you!

    It’s really good, I really like the variety, though I do wish it came with more flanges, I’m a 16 and there weren’t any in the lot

    Ultimate Flange Sizing Kit

    Posted by Callie on 30th Aug 2023

    I am just starting my BF journey and having this kit has given me a lot of peace of mind! I brought it to the hospital with me so that the LC’s could help me make figure out my pumps, and they were so impressed with this kit. They were especially excited that the flanges were all clear so you can see how much of the nipple was being pulled. They said all the flanges they had been using were colored. Thank you for the extra peace of mind in knowing I have all the right options in front of me!

    Flange Sizing Kit

    Posted by Meredith Fowler on 28th Jul 2023

    Love this product!! I recently delivered premature and my baby is too small to breastfeed. After resorting to pumping, I discovered my flanges were way too big for me. Thanks to this product I’m now pumping pain free!

    Love this kit!

    I went from pumping 0.25 to 0.5 oz each time to pumping 3 oz on each side when I got the correct size flange. Love that the flange inserts are universal to all pumps, makes things so much easier!

    Really great!

    This product is great! It comes with everything you need when you start breast feeding! It only comes with a few sizes- not every one on the chart but it comes with common ones most should be able to use. The spray really helps as well!!

    Awesome purchase

    I bought these after having pain issues with the standard size flanges after a few days… the difference the inserts made is amazing! No more pain, better output, and an overall better experience pumping. Highly suggest the sizing kit to anyone before you have the issues I did!

    These little wonders have made my pumping experience so much better. The soft silicone feels comfortable and the inserts helped create a better seal so less leakage in my case. They're easy to clean and maintain too. Giving it 4 starts because it feel like it wasn't clear that the smaller set only has 1 pc of insert of each size.
