Nursi Luna Flange Sizing Kit, 21mm Flange Inserts for 24mm Breast Pumps

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!

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!

These are amazing! My supply has went up tremendously using the correct size flange!

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

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.

so worth it. fits for my spectra & lansinoh pumps. nice having multiple sizes at once because your nipple size can change thru your breast feeding journey

Easy to use and worked well, nice to have all sizes available as shape and size can change often if pumping

This was very helpful with measuring. It made it so easy to figure out what size was needed and having the options ready to go on hand has been helpful. Breastfeeding and pumping can change your nipple size throughout your journey so it’s helpful to have many sizes on hand that can keep the journey a good one!

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.

Me ayudó demasiado la goma que trae para medir el pezón, además trae una tabla que te dice qué medida usar. La extracción ha sido más efectiva gracias a esto. Quedo a mi extractor eléctrico spectra

Good selection of sizes. Quality ok. Very useful.

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.

I used these in my mom cozy wearable pump and they made such a huge difference in the fit, they have fit in every pump I’ve tried so far and the size selection is great as well so I can size up or down depending on what I need
