It was found at the calendar sales booth that a calendar made of new materials was particularly popular. Suddenly, this kind of wall calendar is not much different from the ordinary wall calendar. I just pull it off. In fact, every page is a shopping bag. The reporter looked through the calendars carefully and found that each calendar was composed of 7 pages of non-woven materials. This kind of eco-friendly bag was much thicker than the eco-friendly bags on the market. Can be used as a shopping bag".
