Drafting ruler, dotted line scale MK SIGA JAPAN, 30cm, PAT.P48-58604. This is a Showa-retro used ruler. Please check the condition in the images. The bag has some stains. It has been stored in a dark place for many years, so there is some age-related deterioration such as small scratches, but I think it can be used without any problems. If you understand that this is a used item stored at home for a long time, please purchase it. (Shipping) We will deliver it via Yu-Yu Mercari. Please ask any questions in the comments section. First come, first served.
