To-Genkyo is a Kyoto based studio specializing in product design. Their stated goal is to “make a small utopia of daily life” which I’d say sounds like a good plan. Among their innovative product designs is an hourglass shaped label which reacts to ammonia released by aging food giving a clear visual indication of it’s freshness. Great idea, I hope this actually makes it from concept to the shelves. Sorry, no clue what “milk soap” is.
