I love coffee. I drink at least two cups a day, usually more. I do, however, have occasional pangs of guilt about the number of paper cups I go through.
"I Am Not A Paper Cup" is a well meaning alternative to the paper cup. The cup features two layers of porcelain, which are separated by a hollow cavity that acts as an insulator for hot or cold drinks. The lid is made of silicon.
While it's a nice idea, the fact I would have to carry the cup around with me and that I would have to wash it between drinks, means it's wholly impractical for my daily routine.
