I will never go back to plastic!
I bought the 15mm, 17mm and the 19mm. I used the nipple ruler and I realized I measured at 17mm and with that knowledge I knew I could go up or down 2mm. I tried the 17mm and I fell in love. I started seeing the milk fill my bottles and the sight of that brought me so much joy. I realized that am enough! Flange sizing is so important! I was so pumped that I took my ruler to my sister and she measured at 18 so I gave her my 19mm flanges. I'm so happy I found this! The pictures are from my first time using them. I also love how you can use them with all my pumps. I have a freemie independence, madela pump n style and the madela harmony.
