Flange Inserts 10PCS 13/15/17/19/21mm for 24mm Flanges/Shield of Most Pumps, Flange Sizing Kit Silicone Flanges Insert, Breastfeeding Essentials Kit for New Moms

If I knew about these a month ago, I would’ve saved myself from so my h pain and discomfort. Not only is it way more comfortable to pump! The milk comes out so much faster too 😭🥹 100% recommend!!!!

This is a great set to figure out your proper size, and gives you options if your size changes during your pumping journey. They fit great into my spectra, and made it so much more comfortable when pumping.

A must have! 14 Months of exclusive pumping and our girlies change so much so often these are a must have ! Amazing price too

Works well with my spectra s1. I’ve noticed it’s a bit of a tight fit in the flanges but when using I put a little bit of nipple butter to help slide them into the flange and then it works fine.

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.

Immediately I noticed a difference in the milk output and comfort! My breasts are emptying way faster than before. The sizing chart is super helpful since I had no idea what to look for. I’m using these on my spectra 2.

Nice variety pack. Helpful if you’re not sure what size you are.

I’m not sure if I’m using these wrong but I get really poor suction when I use them with my Spectra, I’ve even tried a few different sizes and none of them work great
