Those cardboard cup-holders from Starbucks not doing it for you? Get the aptly named Cup Cooley from The Container Store. Made out of the wonder material silicone, it's heat resistant, washable and made to last. Add a little edge to your morning cup, and tell the baristas to leave off the cardboard - you're busy saving the trees, thank you very much.
I have one of these and it works so much better than the cardboard sleeves they give you. It is also much more comfortable to hold! stylish, fun, green!
Wow! How I wish they have those in other countries and coffee shops there (because I don't live in the US). It would surely save the trees!
