We designed this kind of paper expecting to remind people to save paper and also protect trees, because paper is made from tree.
Actually, this product will be drew a picture of woods painted around pile of the paper .This picture will be decreased while you taking out the paper which shows you have taken out the life of trees. It is clear to remind people to save the paper with some letters for caring forest on the product. For the manufacture side, it is easily to put in mass production without extra capital and technology compared to existent paper factory.
