Willow 360® 儲乳袋內襯替換組（2入）

Took me two minutes to snap both of these into the milk containers—they click in with a satisfying little pop and hold firm through a full pump session. The two-pack is handy since I can prep bottles in advance without washing between uses.

I was worried the inserts wouldn't stay put, but they snap in with a satisfying click and hold tight through a full pump cycle. Having the two-pack means I can prep both sides at once without scrambling.

These fit my existing containers perfectly and snap in without any fuss. It's great having a backup set ready to go, and they feel just as sturdy as the originals. Nice to have the flexibility without buying whole new containers.
