designer at http://www.ecowritingtablet.com/ . We human being only have one motherland, that is the "Earth".Yet it has been severely polluted in the past decades. Elon musk has great ambition to explore the Mars and make it habitable for human being to settle down. I joined Ecowritingtablet.com, so to help save our motherland, knowing that countless trees were cut down every year to make paper. Because the writing tablet is paperless noting pad, electric drawing board. You don't need to use paper, yet you have good writing/drawing feeling on them.
