Willow 360® 母乳儲存瓶內膽更換套裝（2件裝）

I was nervous about getting the right fit, but these snap in snugly and stay put through multiple pump sessions. The 2-pack means I always have a clean backup ready when I'm rushing between feeds.

The inserts snap in so easily and hold the milk firmly without leaking, which is exactly what I needed for a backup set. Having two in the pack means I can prep both sides at once for night feeds.

Finally got these to try a different volume, and they snap in so securely I never worry about leaks. The two-pack is perfect for rotating through feeds.
