[MUST-HAVE ACCESSORY FOR BREAST PUMPS] Achieve enhanced breast pumping, reduce pumping time, and maximize milk production by using the essential flange inserts for your breast pump. The comfortable and soft silicone material is designed to stimulate milk flow and increase comfort during use. With the added benefits of reduced pain and increased milk output, our breast pump flange inserts are a must-have for any breastfeeding mother needing to pump milk.
[SAFE & EASY TO CLEAN] Ensure safety and maximize the performance of your breast pump with our flange inserts. Made from food-grade liquid silicone and free from BPA, these inserts are easy to clean and dishwasher safe. We recommend washing the pump inserts promptly after each use and replacing them every 2 months to maintain optimal functionality. Plus, receive a complimentary cleaning brush for added convenience.
[CARING SERVICE] With our silicone flange inserts, you receive a free nipple measurement ruler to help you choose the perfect size. Compare the size of your nipple before and after pumping to ensure the most comfortable and effective fit. We provide unparalleled after-sale for mothers by answering your questions anytime and anywhere.
[FRIENDLY REMINDER] Nipple size can vary throughout different breastfeeding stages, requiring different sizes of flange inserts for your breast pump. If you’re aware of your exact nipple size, we recommend purchasing the corresponding size directly. However, if you’re unsure, we suggest starting with our 10-pack of Flange Inserts, which contains five different sizes to ensure you find the perfect fit.
Your order may come with either the new or old packaging, shipped randomly. Rest assured, both versions guarantee the same high-quality product inside.

Great variety and super easy to use!
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!

No-frills variety pack gives you plenty of options
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.

Multiple sizes, great quality and value for money !
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 for testing size
I bought this kit since the standard flange size seems to be 24 which is way too big for myself. I like that it came with 5 different sizes so I could really test and see which ones felt and worked best for my anatomy. These easily fit the flanges in my Zomee z2 and momcozy m5 pumps. The little cleaning brush that comes with it is nice and I also use it to clean some of my pump parts as well as certain bottle nipples.

Just wish I had the sizer before picking pack
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.

Super convenient and good quality
Okay, mamas, this flange sizing kit is a game changer! 🙌 After struggling with discomfort and leaks for weeks, finally got the right fit. The different sizes helped me dial in the perfect one — no more sore nipples or wasted milk. Easy to try, clean, and swap out. If you’re struggling to find the right flange, this kit is totally worth it! And since your flange changes about three times while breastfeeding you can have the new size you need on deck instead of buying new ones everytime.

Wish I’d bought this right from the start!
I wish I had bought this sooner! I had been guessing my flange size and pumping was always uncomfortable — I’d either feel pinching or not get much milk. This little kit made it so much easier to finally figure out what size I actually need. The silicone inserts fit right into my 24mm flanges, and the little sizing tool helped me see that I was using the wrong size all along.Once I switched to the correct insert, pumping felt SO much better and I noticed I was emptying more efficiently. It’s nice that it comes with multiple sizes since your body can change over time too. Definitely worth it for any mom trying to make pumping more comfortable.

More Comfort, More Milk, Less Stress
This flange kit is exactly what I needed! The fit is comfortable, secure, and gentle, making pumping so much easier and more effective. It’s easy to assemble, clean, and works perfectly with my pump. I noticed better milk output right away compared to the standard size. Definitely a must-have for moms who want a proper fit and more comfort while pumping!

J ai commandé en espérant qu il soit compatible avec le tire lait NCVI.Les inserts vont parfaitement dans la bride 24 mm. Le kit est bien complet et chaque embout est emballé individuellement par taille.Je recommande 👍

Lleva dos pares de cada talla y la regla es genial. Es ideal para cuando no sabes qué talla tienes que usar y puedes ir comprobándolo conforme pasa el tiempo, que la talla puede ir variando. Los usé para el sacaleches Elvie Pump en vez de comprarme los cojines. Totalmente compatible con los escudos de 24 mm.

Perfekte Flansche! Sie haben die ideale Größe und pieksen nicht wie andere. Ich finde es super, dass das Maß aus Silikon und nicht aus Papier ist. Es sind verschiedene Größen dabei sowie ein Schwämmchen zum Reinigen – ich bin total begeistert! 💕

Ottimi adatti a tiralatte elettrico Lulia nonostante non sia specificato tra i dettagli del prodotto.Insomma davvero universali.Silicone ben fatto.Peccato solo che si debbano acquistare tutte le misure ed effettivamente con le altre che non vanno bene per il tuo seno non sai che farci e restano sprecare.Sarebbe carino se il produttore fornisse il righello, le flangie singole e la possibilitĂ di restituire quelle che non vanno bene, altrimenti sono sprecate.Comunque ottime e consiglio
