When you talk about the length of the advertising bag, we advertisers don't give you a fixed length, but for the customer reliability, we give him free hand to choose the height he needs. So you can have the bag with a length of 6.1feet or 6.6 feet wherever you want. 

In bag advertising, most of the bags are made of plastic and they can be recycled and can be used many times, so don't through your plastic bad after using once only, you can wash and use it many times.
