This product is an interactive calendar developed to protect forests. The target is people of all ages who are interested in the environment, and it consists of one calendar, a leaf-shaped seal, and a green ink pad. Users will have the opportunity to put a leaf-shaped stamp on the calendar once a day for every time they save on wood disposables. As the user actively participates in saving, the tree in the calendar grows richer and turns green. After one year, the tree in the calendar symbolically shows the fruits of conscience and thrift harvested by the participants during the year.

COSMO-SLOTH, which is a compound word of COSMOS and SLOTH, is a creative research institute that values social purposes. (It means slowly but calmly and endlessly exploring the universe.) We have been contemplating various issues facing the world, such as supporting refugees in Africa and joining the environmental movement. COSMO-SLOTH will continue to present various methodologies and visions that can contribute to society in an artistic and creative way, beyond simple support.
