Stanley’s NeverLeak™ Lid is true to its name. The rotating lid clicks open for easy sipping, and then locks tight for a leakproof seal—so you can safely toss your travel mug into your bag, backpack, or suitcase.

What makes this three-piece lid so innovative can also make it tricky to take apart and put back together. We’re here to help. For complete instructions, check out the following video.
