sunBOX by jinsic kim from korea
designer's own words:
People auslly hang out wet cloths to dry by sunny and natural wind after washing. Although people'd natural method I got this idea. Before when you go out we can just hang out this SUNBOX in a line like your washing. When people gone back to home just take off The SUNBOX from your dryline. The SUNBOX has been charged during the your goingout time.
