Flange Insert 13/15/17/19/21mm 10PCS Compatible with Momcozy S12 Pro/S9 Pro/S12/S9/Medela/Spectra etc Wearable Breast Pump 24mm Flange/Shield, Reduce 24mm Tunnel Down to Correct Size

Perfect for my Spectra S2 and Elvie Stride. Multiple sizes made it easy to find the perfect fit. Holds up well over dozens of uses and sanitization.

The material of these silicone flanges are soft and gentle on my daughter's skin, making it comfortable for her when she is using them. The different sizes help her to choose which one she needs and then the correct one provides a comfortable fit, ensuring efficient and pain-free pumping. They don't cause her any irritation or discomfort, allowing her to focus on expressing milk without worrying about soreness. So far after several uses they have withstood regular use and cleaning without losing their shape or effectiveness. A very nice set for pumping moms.

these arrived today. I am so excited about how high-quality the nipple measuring tool is. It will definitely be better to use than the ones that come with your breast pumps. I think these phalanges will last a long time

Definitely worth it and got more than I used too out of me

Didn’t fit in my Falange hard to insert

This item is exactly as listed and the sizing chart was very helpful and simple to use!

Received today. Well made product but it came missing the 13mm and 15mm inserts.

Fit perfect in my Lansinoh wearable pump. I just got it today and started using it immediately. I got to say for using it just one time already it has been a life changer in a matter of 2 minutes I got about 3 oz in one side and 1 oz on my other side which it would usually take in 20 minutes on my slack side. I totally see and feel a big difference. Love love loveee it already!!!
