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.

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.

This set is a must when trying to find your size. Being able to try before spending tons of money on sizes is well worth the few dollars here.

Must have for breastfeeding/pumping moms. Makes the process much more comfortable. Plus having extra on hand saves you from washing constantly.

I got the momcozy S12 pro through Aeroflow and as soon as I got it I realized I’d need a different size flange than what came with it. The Aeroflow website only allowed you to order individual sizes and I wasn’t 100% sure what size I’d need and I know they can change throughout the breastfeeding journey so I wanted to try and find a multi pack. Amazon to the rescue! These fit and work perfectly with the Momcozy s12 pro and it’s all of the sizes you could possibly need.
