This product is a play-type calendar developed to encourage the saving of wooden disposables and is being distributed free of charge to various educational institutions. 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. In the process, participants realize how much time and effort it takes to grow a tree. This realization raises concerns about the use of disposable wood products and leads to savings.
