Incomplete clips / Office Supplies

People often use clips to reorganize the files, but when a lot of files are piled together, people can’t distinguish which files are completed and which ones are incomplete quickly because of using clips of the same color or different colors. This kind of clips has two colors. The red ones suggest that the files are not completed and the white ones are used on the files which are already finished. Using this way users can easily find the completed and incompleted files, which can improve the working efficiency and makes clips have multiple usages.
