Nursi Luna 21mm Flange Inserts 4PCS for 24mm Breast Pump, Flange Sizing Kit

Accurate sizing and flange inserts. Definitely one of my favorites because they are thick and not super flimsy like some of the other brands on here. I use it with my spectra S1 pump, but they are too long for my Momcozy M5 wearables.

I love this kit!! My flange size has changed a couple times throughout my breastfeeding journey and this kit has all the sizes I have needed. The flanges are great quality and have fit in my spectra, baby buddah 2.0, and momcozy s12. Would highly recommend!

Super helpful!! Fits well in my spectra2

I wish I knew about this product sooner. Fits perfectly into my BabyBuddha 2.0 and made pumping loads more efficient and comfortable. Highly recommend

I purchased the Nursi Luna Flange Inserts to find the right fit for my breast pump, and they have been incredibly helpful. The kit includes 10 silicone inserts in sizes 13mm, 15mm, 17mm, 19mm, and 21mm, making it easy to determine the best size for comfort and efficiency. The soft silicone material is gentle on the skin, and the inserts are compatible with most 24mm flanges, such as those from Spectra and Momcozy pumps.​The included nipple ruler and cleaning brush are thoughtful additions that enhance the overall value of the kit. Many users have reported improved comfort and milk output after using these inserts, as they help achieve a better seal and reduce discomfort during pumping sessions.​However, some users have noted that the smallest size, 13mm, may still be too large for those with smaller nipples. Additionally, while the inserts are dishwasher safe, some users have mentioned that the markings on the sides can be difficult to read over time. Despite these minor drawbacks, the overall quality and functionality make this kit a worthwhile investment for breastfeeding mothers seeking a more comfortable pumping experience.

This was a very good purchase! It includes exactly what is shown in the picture, and it comes with 2 of each insert size. The sizing tool was incredibly helpful in finding the perfect size for me. I also love that it includes a brush to wash everything. Highly recommend for new moms!

Worked great in both my pumps and didn’t make my nips feels raw afterwards! Plus the little sponge cleaner works great for bottle nipples! Came with so many size options and the little silicone measuring tool is so much more comfortable than the hard plastic ones! Definitely great to buy for yourself or for a gift.

Very useful. I love the measuring piece, perfect way to make sure I'm using the correct flange size. No more uncomfortable pumping.

Bought to use with a hand-me-down pump. Immediately made the pump more effective due to actually using the right size flange. The cleaning brush is a good addition and the sizer works well.

The flanges saved me when I really needed a smaller size for my pump. It feels a lot more comfortable now and no more fussing. I highly recommend for pumping mamas

Varias opciones de tamaños y buen tutorial para saber el tamaño correcto

Super soft inserts, they work with both the Spectra S1 and the Medela Harmony hand pump. They’re really easy to clean and the kit comes with a little sponge brush, which isn't the best quality but l if you don’t already have one, it work just fine. The silicone sizing ring is also nice to have so you know what to buy if you’re looking for a secondary pump or just need to replace a flange. Inserts all have the sizes embossed on the neck so even if you open/unwrap them all you’ll be able to know which is which.

Product was fine for my madela swing flex sheild but too smal for my Ardo. Good quality and have sterilised well.
