Review: Great fit & durable quality - I tried a different brand of flange inserts before with some improvement to comfort with pumping but got much better results with this brand/style! I find they fit great into any of the Medela 24 mm flange/shields I took home with me from the hospital and fit good enough in the 28 mm shields that came with my insurance pump (Motif Luna) I ordered when I got home. My nipple size has ranged from 15 - 17 mm so these 16 mm inserts have been very comfortable to use, especially after managing with an 18 or 21 mm flange when I didn't have anything else to use. I've used them for almost 2 months now and have seen no decrease in quality over time.
Review: GREAT FOR FIRST TIME MOMS - This product was recommended to me in the hospital after giving birth by a lactation consultant. After using them to find my correct flange size, I ordered new flanges that fit correctly. Now, milk output is much higher and pumping is so comfortable. After initially using them to find my correct size, I now use them permanently in my portable, wearable pumps. I am so glad these were recommended to me-especially for my peace of mind as a clueless ftm. They are worth it!

### ⭐⭐⭐⭐⭐ Must have as a breastfeeding/pumping mom
*by A***L on July 25, 2025*

As a second time mom I highly suggest this product if you plan on pumping it will help you get an idea of what size flanges & inserts you need for a perfect fit. Keeping in mind your size fluctuates from time to time so it’s best to get a pack of pump inserts in a range of sizes bigger and smaller than your measurement so you can see what works best
