Perfect flangs for any pump
This is just perfect. Different sized flange with a measuring card that helps to identify the correct size you need for the pumps.

They hurt!!
I have tried to make them work by applying lanolin before and after but they are constantly feeling like they are pricking me!! I have angled them but still the pain doesn’t go!! I tried 16mm and then 18mm but still they are not feeling the same. Will throw them away

Much more comfortable than the standard plastic. Easy to insert. Good tight fit to 24mm flanges; doesn't hinder suction. Considering also buying the odd numbers set.

So far so good! they fit into my Frida mom flanges along with my spectra flanges. I don’t know what I was expecting them to be because obviously it says silicone, but I was sort of scared that they would fall out of the flanges but the silicone grips really well and I have no issues with them staying in.
