The Contigo Knox 12 Oz Black Ceramic Travel Tumbler combines two material to benefit from the strong points of each. The inside is porcelain, which doesn’t impart a flavor on your drink and the outside is stainless steel, which insulates better and is more durable.
In between is an insulating foam that keeps your drink hot longer: up to an hour for hot coffee. An insulated grip protects your hand and makes it easier to hold the cup. A lid helps keep in heat and prevents spills and splashes. A non-slip base keeps the cup in place.
This combination tumbler is great for anyone who likes to sip their coffee or tea slowly, especially if it’s during a commute. It keeps drinks hot longer and can take more abuse than a cup that is only porcelain.
I love the idea of combining two materials to get the benefits of both and to cancel out the weaknesses of each. Even better: the tumbler looks great too!
