This drinking vessel aims to do for the disposable coffee cup what Anya Hindmarch did for the plastic bag, and become the must-have eco accessory for 2008. It's made of porcelain with a silicone lid and will see you through cup after cup of coffee without felling any trees.
It's a simple idea but a good one: just make sure you don't leave it on your desk for the cleaners to throw away at the end of a day in the office! Available soon from Decor Craft Inc.

Correct me if I'm wrong, but surely if that thing doesn't have a handle (which it doesn't look like it has) and it's porcelain, it's going to be pretty useless for anything except cold drinks, unless you have asbestos hands. I do like the design though.
It is "double walled" according to the site if you follow the link, so it'll probably be ok for hot drinks actually.
it is double walled and thermal.
it is double walled and thermal so it is made for hot drinks.
