How did we get our start?
Adhering to the brand concept of “redefining comfort with scientific design”, Momcozy has been committed to providing the more comfortable and high-quality mom & baby products in the global market since its establishment in 2017. Most members of our team are mothers with children.
What makes our products unique?
Focusing on the three major areas of quality, function, and appearance, Momcozy continues to optimize product performance in terms of humanized design, material upgrades, and process innovation.
1.Perfect Pumping Experience : The size of the flange is very important for comfortable and efficient pumping. Some moms experience nipple swelling or not draining well due to the unsuitable flange size. With this flange size measure for nipples, it is easy to choose the correct size and get the perfect pumping experience.
2.Best Choice for Pumping Moms : New mothers will be confused about how to choose the correct things related to the breast, such as breast pump and breastfeeding bra. Fortunately, this ruler could save Mom’s time and effort. Say goodbye to the unnecessary pain and stress brought by inappropriate pump with our accurate and helpful nipple ruler.
Easier Measuring Method : This nipple ruler has a great easy and simple way to get a good measure.One is to use the clear scales of the ruler edge and observe the size with our phone or mirror. One is to place the nipple in the maximum circle that can comfortably fit. The 21 measuring holes from 10mm to 30mm which is easy to measure and read.
4.2m Extended Soft Ruler : Momcozy provides a 2m soft ruler which can help you clearly know the body changes during the nursing journey and support body management during postpartum recovery. Besides, this ruler also helps mothers in measuring the baby’s height and healthy growth. It is great to have such a handy tool for many home measurements.
5.Soft and Bendable : Momcozy nipple ruler is made of food-grade silicone, safe and soft, reliable and bendable. Much better than hard plastic or paper with sharp edges, the ruler is friendly to tender skin, offering the best comfort.

Amazon Customer –
If in doubt, buy it.
I honestly had no idea which flange to use! I ended up buying ones that were extremely large and caused me to dislike pumping.Iâm so happy I bought this because it helped me figure out what size I was and which one actually fit. You also get a measuring tape that you can use for other things too.

Must Have
Whew! You donât know how many flanges I went through until I just bought this product! Itâs true to size and super durable. Please save your self time and money and get yourself on of these first before you purchase flanges on your own.

Does what itâs supposed to
Easy to use, handy to have around. Expect to be using this once in awhile to check if my flange size has changed.

Helpful Pumping Tool
Perfect tool to take the guesswork out of making sure you are using the correct size falange while pumping to take out the guesswork of sizing.Your nipples can change so much pre pregnancy, pregnancy, to postpartum – it is nice to have a tool to make sure you are making adjustments to the correct size to keep pumping less painful and efficient!
Jamie Gaita –
It works
It does what it’s supposed to and is maybe slightly easier than using a measuring tape. It wasn’t expensive but for something you’re probably only gonna use once you can probably skip the purchase and just use a tape measure.

So Important for Pumping
It may seem simple but getting your nipple properly measured is SO crucial to the success of your pumping journey. I eyeballed it at first and thought the right size flange for me was 28 mm. I could not have been more wrong! I actually needed 17 mm. Moreover, your nipple size can actually change during your pumping journey, and especially across different pregnancies. Turns out second time around Iâm 18 mm on one side and 19 mm on the other. Get the rulerâ itâs so helpful! Having the proper size flange will make a dramatic difference in milk output and comfort.
