A great tool for new moms
This was so helpful as a new mom to make sure I was using the right flange size in my breast pump. So affordable and easy to use. Measure often as shape and size can change throughout breastfeeding journey.

Good to have!
Perfect for finding out flange size. Very convenient to have on hand, especially because flange sizes can change throughout pregnancy and breastfeeding journeys!
Katie Hershberger –
Accurate
Works as should and measures correctly. I exclusively pumped for me first child and was curious if my nipples had changed sizes since last time. I ended up being the same, but the tool confirmed it.

Great Item, Ended Up Not Needing It
My friend had this and let me borrow it when I started breastfeeding. It helped me to accurately find my flange size which was so beneficial in having a more painless experience and saved me a lot of time and money.I ended up purchasing one of my own to have on hand so I could continue to measure as my body changed, but ended up switching to exclusively doing formula and never used it. Because of this I ended up returning it, but I would highly recommend to anyone who does need something like this!.It’s accurate, and easy to use!

Vital for new moms
As a second-time mom, I wish I had known about the importance of properly sized flanges with my first babe. I struggled for three months with breastfeeding and pumping for my first baby – having the proper size of flange would have changed everything for me.â Easy to use: itâs very self explanatory and provides the size needed for flangesâ soft, flexible measuring device – something that is so important for an area that is so sore in those early daysâ Good price – comparable products were overly expensive and didnât seem as comfortable

know your flange size
This helps you figure out what size you are so you can choose the correct flange size for your pump. it is made of a durable silicone, so you can clean it easily and not worry about tearing it accidentally like the paper measurers

Must get if lost on flange size
Worth the but if your ever lost on what size your nipple is to fit the pump. I was lost for a while. I wasnât pumping enough and then I read that I may have the wrong size flange. So then I got this, measured and got my size. Ever since then, no issues.
