I am SO thankful I ordered this brand, I originally ordered the 24mm and it was definitely too big. I only knew this due to the paper you see immediately upon opening the package. I have been using the standard 24mm size on any pump I have tried and never had pain but never got much milk either. HUGE difference with this and I even think I could go down a size but unfortunately it looks like this is as small as they come.
