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

Great product if you need to change your flange size due to your Medela pump having flanges that are too big. I got this to try out a few sizes because ‘the girls’ have changed so much postpartum- who knew! These are the inserts that have to be used in a flange that is larger sized like a 24. I figured out that the inserts don’t work as well for me but there’s a lot of trial and error in my breastfeeding journey.Anyways this is fantastic quality, a great price and the includes helpful things like a nipple measurement tool as well as a cleaning tool.Overall- Highly recommended if you want an insert for your flange and you need to figure out which one works best for you.

Absolutely changed the way I was pumping! If I could have put one thing on my registry for personal items, I would have added this. The flanges made such a huge difference in the way I was pumping. All the flanges are super soft and fit right into the breast pump. I personally used the spectra 2 and had no issues with it. It comes with a convenient little brush to clean them after use. The sizer that comes with it as well is easy to use to know what is the right size for you. Each baggie is also labeled as well so there’s no confusion which helped a lot and there’s many different sizes.

I was really impressed with these flanges! They came in a bunch of different sizes, which made it easy to find the perfect fit. I also appreciated that they included a measuring tool to help figure out which size I needed—super helpful for someone unsure where to start. Plus, the cleaning brush was a thoughtful addition and made cleanup simple. Overall, great quality and a very convenient set!

Great product just wish it was a clear material

I love these flange inserts so much! I was struggling with my supply using my pumps so I decided to purchase this product for the new sizes + the silicone sizing mat and WOW! As soon as resizing myself I have been able to get so much more milk. They are also so easy to use and clean and super comfortable!!! Would definitely repurchase and also recommend for friends registries!!

It was suggested by my lactation nurse to size for flanges. She said most people aren’t using the correct size because most pumps only come with 2 sizes. DO IT!! Being able to check my size is eye opening. I was using the 24mm flange that came with the pump but sized down to 17mm with this kit. That’s a huge change and makes the pump more comfortable to wear. This is worth the money! Also, it’s FSA eligible!

I love this kit. Im a first time momma and had no idea what my flange size was supposed to be nor did I even realize women have different nipple sizes..10/10 recommend. Super easy to use and understand.

i want to like this sizing kit but when i received it i ended up with two 19mm and i am missing the 21mm size. Sadly this is one of the reasons i bought this kit was for the 21mm size.the measuring tool is very nice though and the sizing information is very helpful. the other pieces seem to fit in both my 24mm pumps. it is hard to get both 19mm to fit though but hopefully they will work.
