This is pretty intense...

It's a pen cap that doubles as a biodegradable spoon, knife, or fork. I'm not all too sure about what I think about this, but it definitely is an interesting idea. If you would like more information, here are the designer's word:

Turn your favourite office tool from your desk in a common cutlery...this is din-ink. A set of pen caps, including a fork-cap, a knife-cap and a spoon-cap, that replaces the normal pen cap during lunch time! All caps are made by annually renewable resources, like natural starch and fibres, to be 100% biodegradable and atoxic, warranting the best alimentary use. Dispensing each set in a compostable packaging the whole set is designed to respect the environment. Now give your office ballpoint pen a good excuse to be gnawed by your teeth: use them for din-ink.

And to purchase some, well, you'll just have to wait until they actually start manufacturing them. :P
