Best manual breast pump

Alexandra • Mom to Charlotte Amelia and Levi Patrick 👨‍👩‍👧‍👦 Married to my soulmate ❤️

I’ll be on a plane for 10h+ and need to pump. I already have the spectra s1 but want a manual for the ride. Which pump has smaller flanges? I have 17mm flanges for my spectra.. yes, really small. Any advice would be appreciated 🤗
