an ashtray in the cigarette case by kyu-sun lee from korea

Cigarette butts can be found near the side streets, crossroads or the taxi and bus stops. Especially, there are more smokers who throw away cigarette butts around the bus stops when the bus they wait comes. I considered how to reduce the cigarette butts on the street when I saw those. It is responsible for cigarette companies and smokers. There is the way, an ashtray in the cigarette case. The roads will be cleaner and smokers do not need to find trash cans on the streets by making an ashtray in the cigarette case.
No need to reduce the number of cigarettes in one cigarette case. The slide type ashtray in the bottom of the cigarette case can simply be made.
