Perfect
Our originals started getting gross so I ordered these as he should be coming off the bottle soon and didn’t want to spend a lot on all new bottles. They fit perfectly

Cut to size
For some reason, wide neck vents do not exist for 5 oz bottles?? I bought these and used a hot knife to cut/melt to size based on the originals. It worked, but I don’t feel like I should have to MacGyver my baby bottles. The vents were good quality.

Perfect replacement
My other ones melted in the dishwasher and these were a great price for the replacement.
