I am always amazed at Japanese products. You have to give it to up to the product and industrial designers over there, they really know how to make their goods cute, practical and efficient.
First up, is this interesting little thing from a company called "Brook's" which is Drip Pack Coffee where you can enjoy drip brew coffee without the use of a Drip Coffee Maker.
Its like coffee in a coffee filter.
These things actually foldout like wings
Then continuously pump hot water, waiting as the water drip out the filter.
There are a lot of flavors and blends available.
