隔膜（2入）僅適用於穿戴式吸乳器

These fit perfectly and swapping them in took less than a minute. My tubing has stayed completely dry since I replaced the old ones, and the milk never backs up toward the motor anymore.

My pump motor finally stopped smelling like old milk — these diaphragms actually do their job keeping everything dry and clean. The two-pack means I always have a spare ready when one needs washing.
