Will this fit a standard size bottles such as Evenflo or Lifefactory?

These fit (and work great for) both the 4oz and 8oz size of GLASS Evenflo bottles. We have used them for normal storage as well as freezing.

Do these fit on the green Options bottles?

They fit the bottles, but you have to remove the straw and everything else first.
