01 We wasted too much paper in our office and most of used paper is not classified. We can reuse it for other purpose. 02 Once our pen run out of cartridge, most of the times we will drop our point-pen in trash can, causing a tremendous waste of resources. Rolling green transforms wasted paper to pen. We have plenty of useless paper in our office. Thus, We can buy pencil lead and point-pen cartridge, then, using Rolling Green to transform them to pencil or point-pen. Advantage: 01. Save disposable resources in our office. 02. We dont need to spend more money to buy point-pen and pencil.
