Portable Clear Book / Clear Book

Folder is one of the most commonly used office supplies. Although it is relatively easy to classify and store files, but the shape of varying thickness on both sides makes it not convenient for carrying and transporting, especially with large amount of them. The Portable Clear Book adds two folding handles to the inside edges of the existing folder. The handles can be turned out to carry several folders. They can be folded inward to fix file or serve as bookmark during reading. This small change makes the folder more convenient and comfortable for use without increasing cost.
