Say Hello to your new favorite sidekick - the 12 ounce Yellow Polar Tumbler that definitely doesn't give a sip! With a cheeky engraved message and sunshine-yellow attitude, this double-walled, vacuum-insulated tumbler keeps your drinks ice cold, or piping hot. (It also keeps wine at the perfect temp). So, no matter how savage your "sass" is, perfect for those wine rebels, tea & coffee lovers and anyone that owns their sarcasm like a badge of honor.
