These lids are replacement lids for the canteens. Please be mindful ta these lids are for the canteens with the straw that goes INSIDE the lid hole. The 20oz lids have a lid with the straw that goes on the outside of the hole. We knownthe 12os lids have straws that go inside but some of the 32oz lids do as well. Just be sure to check your top to the picture to be sure it will fit your straw.
