Arizona State Sun Devils 40 oz. Handle Tumbler

I’ve had my tumbler for about a month and loved it. However, after recently removing the lid to wash the tumbler (not for the first time), I can no longer get it to seal properly. The previous times I’ve washed the tumbler and lid, the lid sealed just fine. This time—despite the rubber ring being in place—it won’t. with every tilt or jostle, the tumbler is leaking. Would really like a replacement lid that will remain sealed and prevent spills.
