I’ve only used the Stanley a few times however, the lid dropped on the floor and my dog took off with it and she chewed on it just a little bit before I could get it from her. You could probably take a piece of sandpaper and sand it down and no one would be the wiser or get a different lid .. , I just don’t find that I use it very often and I know these are a hard find so I figured I would let someone else enjoy it if they wanted one and for a discounted price… So it’s sold as is!
