Who needs reusable when you have an edible coffee cup made out of a cookie?
I feel like crying decaf.
As seen on Design Taxi, check out this espresso cup made out of a cookie.
I like coffee. I like cookies. (Guess how many cookies I ate today? If you guessed 12, bad news: You're not a wizard.) So naturally, I love a coffee cup you can eat. The cup has an insulated interior made of sugar icing which makes it waterproof - and more delicious.
It might take some effort to explain cookie coffee cup to my dentist but I'm too cowardly to go anyways. I also worry about crumbs in my beard. I'll get over it. This idea is just too weirdly blissful to pass up.
