09-08-2025There are so many size options in this kit! Not to mention the card that helps you measure and learn how to measure if you’ve 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!

09-08-2025If 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!

09-08-2025This is my sixth baby and somehow the first time I’ve 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 you’re pumping and not sure about fit, just get this. It makes a big difference in comfort and output.
