Babyglazen flessen met standaard hals en schroefdraad - tweepak

The polypropylene material feels sturdy enough to hold up to daily washing. My standard neck bottles finally have a reliable seal again, so no more frustrating leaks during overnight feeds.

I was worried the original threads would wear out after daily washing, so having two spares on hand is a relief. The polypropylene feels sturdy and they screw on just as snug as the ones that came with my bottles, no leaks so far.

These screw threads fit my standard neck glass bottles perfectly, no leaking at all even when I shake formula. The PP material feels sturdier than the flimsy rings that came with my old bottles. Two in a pack is handy so I always have a spare while one's being washed.
