Highly recommend for any breastfeeding mommas!
There are so many size options in this kit! Not to mention the card that helps you measure and learn how to measure if youâve never done it before. There are a few flanges to choose from that will suit your size and if not you at least have the measuring tools to order your specific size as everyone is different!

Breast Pumping Must!
If you are a mom who pumps but are struggling with supply, pain or fit- BUY THESE. This has been a game changer. It comes with a flange measurement tool to ensure you are using the proper size. This comes with several sizes so you can see what works best for you. The flexible pieces fit right into your pump shield. Easy to use!

Wish I had this with baby #1
This is my sixth baby and somehow the first time Iâve ever measured myself for pumping. I really wish I had done it sooner. The sizing tool is super simple to use and gave me a clear answer on what I needed. The set itself feels like a great value, especially with all the extra inserts included. If youâre pumping and not sure about fit, just get this. It makes a big difference in comfort and output.

Great for new moms!
Great kit for a new mom! Had the sizing measurements, plus different sizes of flanges to try out. Flanges are on the smaller side, so if you have some elastic to nipple could cause some friction.

Great Variety and Handy Extras
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 neededâsuper 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!

Helpful!
I was feeling overwhelmed by the bf journey and learning i needed to be sized was just another thing to add on the stress so it was nice being able to do it at home! The sizing tool is soft and flexible and it comes with a small variety of options for you to try. It also came with a small sponge for cleaning (although i just use the bottle brushes instead)

Mixed review
The measuring piece was great! Helped me find my right size. The inserts didnât fit super well into the existing flange and hurt my breast when pumping. Ended up just getting a flange in my correct size and it works great!
Lydia Harrison –
Would recommend to anyone pumping, standard flanges on breast pumps are way too big and stopped me from pumping. Would have pumped more if I’d had these from the beginning. The nipple measurement guide really helps with gauging size. Easy to clean, I washed with hot soapy water and threw in the steriliser.

Perfect!

Es súper variable y se adecuada a tu medida
Jake –
These certainly helped up the amount of milk extracted each pumping session. The flange size makes a difference to comfort too. My wife made plenty of use of the size that she found to be right for her. This set included every thing needed to correctly size.
