Nuliie10PCS Flange Sizing Kit 13/15/17/19/21mm for 24mm Flange/Shield of Most Pumps, Silicone Flanges Insert for Momcozy/Spectra Electric Breast Pumps, Pumping Essential Kit for Moms

I had no idea how much the wrong flange size was affecting my pumping sessions until I tried this kit. The Nuliie Flange Sizing Kit made it incredibly easy to find the perfect fit for my needs. The variety of sizes (13, 15, 17, 19, and 21mm) allowed me to experiment and discover which one provided the most comfort and efficiency.The silicone inserts are soft yet durable, and they fit seamlessly into my 24mm flanges. Cleaning is a breeze, and I appreciate that they’re BPA-free. The included nipple ruler was a thoughtful addition, making it straightforward to measure and select the right size.Since using the correct size insert, I’ve noticed a significant improvement in milk output and a reduction in discomfort. This kit is a must-have for any pumping mom looking to optimize their experience.

This kit was extremely helpful in finding my proper flange size for my breast pump. Once I found the right size, I now place the silicone flange inside the larger plastic 24mm flange that attaches to my breast pump. The seal is great and works perfectly! Easy to clean and sterilize too.

I got this flange measurement set to use with my Medela pumps (which all fit 24mm), and I'm really happy with it. I wanted a variety of insert sizes in case my needs changed, and this set delivered. The inserts are definitely more comfortable than pumping without them, and I love that I can include them in my regular sterilization routine.The set came with a small foam brush (handy for cleaning), a measurement card with sizing holes, and a pair of inserts in different sizes. Everything feels well made, and it's a great value if you're trying to find your best fit.

This was so helpful after my son was born. The lactation consultant in the hospital didnt tell me about these. When I came across it online somewhere I knew i needed to get them. Helps so much with pain or discomfort while pumping, great value for the price. The flanges even come in pairs so you don't have to buy two.

These flange inserts are a game-changer—soft, easy to clean, and fit perfectly in my wearable pump. The included sizing ruler helped me find the right fit, boosting comfort and milk output. Only wish they offered more size options.

I ordered this kit to size myself for pump inserts. It was very useful to find the right size and had everything I needed. The inserts fit in my spectra pump and my mom cozy v1 pro pump. They’re easy to insert and easy to clean. I also like that it comes with multiple sizes for when my nipples are chewed up and swollen from my newborn!

This kit was suggested to me by a nurse. I needed more size options and this works perfectly. Love that the sizer is included.

Really love this set! Comes with 2 sets of nipple measurements and many different size flanges to choose from. They’re easy to insert and clean and good quality!
