Twice / Daily necessities


Every day, countless garbage is produced around the world. The excessive consumption of resources overwhelms the system of the garbage cycle. Meanwhile, the poor are facing the lack of subsistence resources, compression of living space and deterioration of environmental quality.
“Twice” is not only a dual-use mask, but also an idea that we want to spare among people. It is the people’s awareness of frugality that we want to evoke by “Twice”. So that there would be more opportunities and resources for those who is surviving at a subsistence level.
