I bought this strange "clear file" from the dollar store the other day because I wanted to figure out how it worked. It has a strange mechanism inside that I just don't know what to do with. I have been messing with it for awhile now and decided I needed some help. The file says "Mingyu" makes it and "Made in China". Written across the front is "MINGYU OFFICE THING SERIES" if that helps.
