Review on Tervis Warner Brothers Friends Pattern Insulated Tumbler - 16 oz Clear Cup with Wrap and Black Lid by Mike Newbill

Finally got my cup yesterday and I'm so happy because I'm such a big fan of friends. BUT. It's leaking! I didn't even tip it, I just held it in my hand and walked away! And when I squeeze the leash, more of my coffee comes out. I didn't fill the cup so it will overflow or something. very disappointed. One star for the leak and 2 stars for the cute design. I want to keep the packaging so I can send it back. Do all mugs from this brand leak when advertised as sealed?
