Nuliie8PCS Flange Sizing kit 21mm for 24mm Flange/Shield of Most Pumps, BPA Free Silicone Flange Inserts, Compatible with Momcozy/Elvie/Spectra/Bellababy/TSRETE/Nuliie Electric Breast Pumps

Summary: it’s exactly as advertised. You get a variety of flange inserts to test, a very handy brush to wash them, and a nipple guide to measure. Easy, straightforward, can’t go wrong buying the variety pack.More detail: it’s packaged well, each set of flange inserts comes in its own plastic packaging in the box. On each insert, the size is printed on the rim of it, so it’s fairly easy to see what size you’re working with.The included brush makes it much easier to clean, especially if you get bits of milk stuck around the edges, which is pretty common for me. It’s difficult to get it fully clean when using a traditional bottle brush, but the included brush is made of a soft material that really gets the milk off.It fit perfectly in my spectra flanges, and fit pretty decently in my Mandela ones- it just needed a little bit more finagling to get a flush fit.This was a good way to test out a variety of different sizes quickly.Tip: the silicone can stick a little, and create friction on your sensitive areas. A dab of coconut oil on your nipples before you pump, and you won’t have this problem.You can also apply the oil directly to the flange insert, but it gets a bit messy. Putting it on your skin is just as effective, without making the flange overly greasy.

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.

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 love that everything is Included in this kit. Do you can just measure with a silicone tool (nice because it’s washable) and then pop in the correct flange size insert! Perfect for new moms or even for a gift!

These fit perfectly into my pump and they help a lot with pumping. Makes it very comfortable

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!
