Will these only fit the options bottles?

The bottles themselves are all the same. So these will fit any bottles. I’m not 100% sure if the cap that holds the nipple will fit from the natural flow, but I’m sure it will.

will these fit evenflo bottles?

Thank you for your inquiry. We have not tested the Dr. Brown’s Natural Flow® Options+™ Replacement Vent Kit, 2-Pack, Narrow in an evenflo bottle.

Can someone please tell me what these pieces are called?

The parts in this post are the travel disks, reservoir tubes and vent inserts.
