It's from Japan's street trash sample.
I like the idea because when foreigners come to Korea, they can't even read Korean.
If the trash and also the bag inside are transparent. It can easier to recognize what kind of rubbish sorted and also convenient the rubbish collector to see inside.
Also Iwould suggest to add a cup collector like this, because korean like drink coffee, lots of coffee cups are left on the street. If we can collect the cups by overlapping the used cups, it can save space.
