Replacement for original cap. Warped the original after putting it in the freezer with the thermos. Fits great and fast delivery. Glad they make replacement parts!

This is my husband's second cap. The plastic broke on the first one.

This was a perfect replacement for my old top, which broke after a long time of carrying it every day by the handle. I was a little worried about fitting it over the lip, but it only took a little "encouragement" with a narrow tool, and it fit right on, just like the old one. Thank you!
