Clean the City , Cleanse the Earth / A Cigarette Filter recycling Box

Clean the City , Cleanse the Earth
Clean the City , Cleanse the Earth

Our design features three changes to traditional cigarette boxes.
We’ve cut the width of the mouth to reduce the amount of cigarettes taking out each time.
We made an extendable inner storage, which extends 9 times than its original size, easily storage whole 18 cigarette butts without changing the size of the outer box.
Third, a plug to not only stop the smells from leaking, also increases the tolerance of our inner storages opening.
With our filter recycling box, there’s no need to spend time finding the nearest trash can, no more manholes covered by cigarette butts. Stop flicking it away, put it in, let’s clean the city, cleanse the earth.
