ฝาปิดปั๊มนมซิลิโคน

The seal is nice and tight, so I don’t have to worry about dust settling on the flange between sessions. It snaps on in a second and stays put even when I toss it in my diaper bag.

Snapped this on right after washing my pump and it fits the Generation series perfectly, no wobble or gaps. The silicone is thick enough that I don't worry about it popping off in the fridge.

The fit is snug enough that I don’t worry about it popping off in my diaper bag, and it’s nice not having to rinse the pump every single time before I use it. Cleaning it takes two seconds too.
