The Nursi Luna Flange Inserts (10PCS) work great and fit perfectly. They’re soft, comfortable, and helped improve suction while pumping. Easy to use, easy to clean, and very helpful for getting the right flange size. Great value for the price—definitely recommend!

Great quality! It came with directions for sizing that were easy to follow and helped me find my fit. The inserts are easy to clean and put in and take out of my pump. I’ve always despised pumping because it was uncomfortable and made me sore afterwards. I was using the 24mm flange that came with my pump until a lactation specialist suggested these. Turns out I needed a much smaller size flange. Finding the right size helped with pumping pain and increased my milk output! If this honest review helped make your decision, please mark it helpful!

Sizes and the size chart work as intended

Didn’t realize how much I needed them until I got them. Fit perfectly in all my pumps. Great quality

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.

Wonderful product has a large array of sizes and helps you be able to try what will work best for you

Nursi Luna Flange Inserts 10PCS – Super helpful for new moms! Functional, durable, and easy to clean, with multiple sizes to fit different pumps. Great value for breastfeeding essentials.

I appreciate this so much. I was a FULL YEAR into pumping before I realized my flange size was wrong. I didn't want to guess my size so this set was so handy. Turns out I was using a flange almost 4 SIZES TOO BIG! Once I started using the right size it was so much more comfortable and my output was better. The inserts are nice quality and easy to use with my pump. This was so worth it!
