sunBOX by jinsic kim from korea

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.
