It has many small scratches. Only for those who don't mind. Scales are 1mm and 0.5mm Total length approximately 524mm (there is a margin of about 12mm on each end) Thickness 5mm This is a long ruler, not often seen these days, with high precision 0.5mm pitch, and a substantial 5mm thickness. The 0.5mm pitch is said to be convenient for drawing scaled drawings. This is a novelty item from the now-defunct Tomen Construction Co., Ltd., which supported Japan's infrastructure. It's a legacy from the days when Japan's drafting and design fields were done by hand, and may be a valuable collection piece that speaks to the design culture and tool history of the time. It will not fit in a mailbox. It will be wrapped in bubble wrap and paper, and sent from the weekday post office counter via non-standard, non-standardized mail. If you wish to have it handled as fragile, it will be an additional 300 yen. Please let me know in the comments. Body weight 133g
