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

This is the second set of flanges I've purchased but definitely my favorite. They are comfortable and easy to use. Also they cone with a size chart which is vital in knowing which flange to use. I'd buy another set from this brand if needed because they are great especially at this price point.

My lactation consultant recommended that I get a pack of different sized flanges for my breastfeeding journey. She said your nipple can fluctuate in size as your baby ages. I like that this pack had a variety of sizes. They easily fit into the pump flanges that I have (spectra 1 pump). I am using them daily and they are holding up well even though the material seemed kind of thin. Very easy to wash.

I love this kit! Sometimes it’s easier to have the flange sizes in person to see which fits best.

Help with not having to buy a million flanges and it saved my nipples. #savethenipple

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.

Good

Great for newborns

the kit came in a frosted silicone, and were a thicker material which I really liked. I then ordered the separate sizes and those came in a thinner clear silicone which I didn't like. I would give the kit a 5 star, but the separate sizes would get a 2 star. hence the 3 star.UPDATE: the company reached out to offer a refund, which I think shows good customer service.
