If you’re thinking in your brain, “Why in the crap should I buy a cup online?” you’ve never owned a Tervis cup.
Tervis cups are one of those things you use at a friend’s house and think, “What the deuces is this thing and why does it look like it’s two cups in one?”
And then after using it you say to in your head, “Holy moly, my drink actually stayed COLD while I nursed my drink! Where can I get my own one of these cups that have a lifetime guarantee, are dishwasher and microwave safe, and are made in the U.S.A.?”
See? I told you so. You totally want a Tervis cup.
