Nursi Luna 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

Absolutely perfect. They come with a nipple size chart which meant instead of having to get a tape measure out like other brands wanted I could easily just slot it into each hole to figure out what size I was and which flange I needed. It comes with multiple size options and easily slotted into my breast pump. It was exactly what I needed.

These are amazing as they have a number of different sizes to choose from. Great value for money!

Great for my momcozy s9 pro

I purchased these for my tommee tippee electric breast pump and they have honestly made such a difference. There is virtually no more pain/discomfort from pumping now I have the correct flange size. Would definitely recommend.

These are really good with my medela freestyle hands free. I didn’t realise I was wearing an incorrect size. The only downside is that these are not clear so you cannot see the nipple to ensure correct fit, hence 4 stars.

Got the box as i was unsure what size flanges i needed. Good instructions and quality flanges.

The item is not soft-touch material, it causes irritation.
