  • Perfect fit and essential for pumping
Size: 13/15/17/19/21mm-10PC
These flange inserts are a total game-changer for moms using wearable breast pumps! I struggled with the standard 24mm flanges being too large, which led to discomfort and reduced output. These inserts helped me size down to the perfect fit, making pumping so much more efficient and comfortable. Why I Love Them: ✅ Great Compatibility – Works perfectly with my Momcozy S12 Pro, and I love that they’re designed for multiple pump brands. ✅ Better Suction & Comfort – No more pain or discomfort! The proper fit has made a huge difference in my pumping sessions. ✅ Easy to Clean & Durable – The silicone material is soft yet sturdy, easy to wash, and holds up well with frequent use. ✅ Great Value – You get 10 inserts, so I always have extras on hand when I need to swap them out. If you’re struggling with flange fit and need to size down, these inserts are a must-have! Highly recommend for any pumping mama looking for a more comfortable and effective experience. ... show more

  • Lots of Sizes
Size: 13/15/17/19/21mm-10PC
I love these inserts, there a several different sizes and 2 of each size. I was able to find the correct sizes for myself and they fit perfectly in the different pumps I have. However, you need to use a 24 size flange for them to fit properly. They are too small for a size 28 to fit.

  • GAME CHANGER
Size: 17mm-6PC
The way these drastically changed my supply. Was having the hardest time emptying out until I read the size of these mattered. Had to guesstimate what size to get but GAME CHANGER once I figured it out!

  • Great quality.
Size: 13/15/17/19/21mm-10PC
Great quality and easy to clean. Lasted the entire time I pumped so about 6 months. Helps you find your size and you have other sizes if your nipples change.
