Muji Aluminum 15cm Ruler. This item was part of a collection I had during my student days, but it has been sitting in a drawer, so I'm putting it up for sale. Unlike the currently sold version, this is a discontinued model with black printing. Please note that, as shown in image 2, there are scratches on the back (including fine scratches) that appear to have occurred during storage. Also, it has been stored at home for a long time. Therefore, I would appreciate it if you could understand this before purchasing.
