So, I hope your are looking at this because you have some clue as to what it is. I think it attaches to the side of your computer for some unknown reason. It is written in some sort of possibly oriental script with very little English. There is a ruler on the side, possibly in centimeters. The entire thing is 12 3/4" long and 3 1/8" wide. It is made of plastic. It is new in the plastic. Thank you.
