10PCS Flange Sizing Kit 13/15/17/19/21mm for 24mm Flange/Shield of Most Pumps, Silicone Flange Inserts Replacement Kit, Pumping Essential Kit for Moms

This silicone flange insert kit has been a lifesaver for my pumping routine. The variety of sizes (13/15/17/19/21mm) makes it really easy to find the perfect fit for comfort and efficiency. The inserts are soft, flexible, and easy to snap in and out of my 24mm breast pump flanges, so switching sizes or cleaning is hassle-free. I also love that it comes with multiple pieces, so I always have backups ready. Overall, it’s a practical, high-quality kit that makes pumping more comfortable and customizable — definitely a must-have for breastfeeding moms!

I love that it includes multiple sizes (13, 15, 17, 19, and 21mm), which makes it easy to find the perfect fit without having to buy separate inserts. The sizing variety is especially helpful for moms who are still figuring out what works best for them. The silicone is soft, flexible, and very comfortable against the skin. Once inserted into my 24mm flange, it stayed securely in place and created a better seal, which noticeably improved comfort and suction. Pumping felt less painful and more efficient compared to using a standard hard plastic flange. Cleaning is simple, and the inserts seem durable even after multiple washes. This kit is a great value for the price and perfect for moms who want a more customized, comfortable pumping experience. Highly recommend for anyone using 24mm breast pump flanges who wants better comfort and fit!

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.

Lots of options out there. This worked for me. Liked the brush and measuring tool. Appreciate the various flange sizes in the pack. Fit Spectra and Momcozy M5. Wish this came in a case but overall would recommend.

I didn’t realize how much of a difference flange size made until I used this kit. The Nuliie Flange Sizing Kit helped me find the perfect fit and completely changed my pumping experience. Definitely noticed more comfort, better output, and way less frustration. The inserts are soft, high quality, and easy to clean. I use them with my standard 24mm flanges, and they pop right in without any issues. I love that they’re BPA-free and come with a clear nipple ruler for measuring, which made it easy to finally understand what size I actually needed. My only complaint: the inserts come grouped in sets like 13/15/17/19mm, so I didn’t know which set to buy before getting the sizer. I wish I had known to start with the ruler first it would have saved me some trial and error. If you're a pumping mom dealing with pain or low output, this kit is absolutely worth it. Just be sure to measure first.

This set is really convenient. I had heard about elastic nipples and spent $75 on a pumpin pals set, but I found the sizing confusing and didn't really feel like it worked better. I liked this set much more! I like having the ruler, which let's me know how my nipple size is changing during a pump, and I like the silicone inserts which are really convenient to swap in and out including in the middle of a feeding. Works really well, easy to clean.

The flanges are of silicone and great quality. You get a pair of each size, a ruler to measure, and a brush to wash. It is compatible with Spectra S2 and Medella manual hand pump. It is packaged really well, with individual packing. The brush is soft and cleans well, hence no scratches either on the flanges. It is a great value of money, since you're getting a variety of flanges in very less cost. The measuring tool is a silicone one as well as a paper on. Unfortunately I was in between sizes, so I contacted customer support and they got back to me with prompt responses. Great customer support, they were very kind to offer me a free replacement of the other sizes. You should go in for this product as it lets you play around with different sizes at a fraction of cost.

Great price! The flanges have held up well and worked amazing in my hand pump, portables and my spectra! Absolutely worth the buy!
