Willow 360® 防漏母乳袋（48入）

The self-sealing closure on these is so solid I’ve tossed a full bag into my diaper bag sideways without a single leak. The 48-count has lasted me nearly two weeks of daily pumping, and the direct-pump connection saves me a whole transfer step.

Pumped into these directly and not a single drop escaped when I pulled the bag out to stack it in the freezer. The self-sealing strip locks tight every time, which honestly saves me a whole towel and clean-up session each morning.

I was skeptical about the no-spill claim, but the self-sealing mechanism really works—no leaks at all in my bag. Perfect for pumping directly into storage without any mess.
