Introducing our new thermos from Fellow - the Carter mug! At 12oz, these thermos are especially great not only because of the collage of illustrations but because the inside is entirely ceramic. No longer will your coffee forever taste like metal!

New this run is the introduction of the Slide Lid. This is the best of both worlds because it is both leakproof and spill proof while drinking. The lid stays attached but simply slides out of the way to take a sip through the sippy cup lip. Moving around and not drinking? When it's slid closed the vessel will not spill even when turned upside down!
