Nuliie 3-in-1 Flange Sizing Kit 13/15/17/19/21mm for 24mm Electric Double Breast Pump Flange/Shield, 10PCS Silicone Flange Inserts to Boost Pumping Efficiency & Comfort, BPA-Free Essential for Moms

I’m so glad I found this flange sizing kit—it has made a huge difference in my pumping experience. The silicone is really high-quality, soft but durable, and super easy to clean, which is a must when you’re using something this often. I love that it comes with both a sizing chart and a conversion chart. It took all the guesswork out of figuring out the right fit, and having everything included made the process so much less stressful. The little cleaning tool it comes with is also such a thoughtful bonus—it makes keeping everything sanitary quick and easy. The biggest difference for me has been comfort and output. Since using the correct size, I’ve noticed a significant increase in my milk supply and way less pain while pumping. It’s honestly been a game changer. If you’re breastfeeding or pumping and unsure about your flange size, I highly recommend this kit. It’s simple, effective, and made a noticeable difference for me right away.

I recommend this kit for ANY new mom. This flange sizing kit was super helpful and made figuring out the correct size so much easier. I love that it includes multiple sizes all in one kit, especially for new breastfeeding moms trying to get the best fit for comfort and output. The material feels durable, the measurements seem accurate, and it worked well with my pump setup. Definitely a useful little tool to have before spending money on multiple flange inserts that may not fit correctly.

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.

All I can say is get it! I didn’t want to splurge on an expensive flange sizing set and this kit was perfect for not only helping me find my correct flange size but the inserts are also made of a very soft and flexible silicone which is nice for pumping because you can’t even tell it’s there!

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.

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!

As a first time mom not really knowing what I’m doing this kit was super helpful. Different flange sizes and a measuring guide to make sure you’re getting the best fit. Flanges are comfortable too, flexible and not too stiff.

The flange sizer is a nice silicone so it can be reused if needed! Came with all pieces as well! Works amazing with my Medela manual pump!

Super pratique et s'adapte parfaitement avec les tetrelle medela

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.

Highly recommend these for pumps so much cheaper than the big brand names and found they last just as long.
