One Day, in 2012, I wanted to help my daughter wrap her books, and tried to find some good book cover. Unfortunately, I could not find anything that met my demand. Everybody was selling PVC book covers which has strong smell, and my daughter is very sensitive to smell, which makes me very upset. We are in the office and stationery business for more than 15 years, but I even could not find a good book cover for my daughter. And the environment pollution in China is so serious at that time. My daughter got sick every week due to the bad air. Since then I decided to move our focus from commodity products to Eco-friendly Office Supplies range.
