Sanko Seizu Kikai Seisaku Co., Ltd. Draupnir Board Parallel Ruler Drafting Board This item was used for the architect exam a while ago. During storage, the protrusion on the cover of one of the adjustment screw covers broke, and the cover came off. The adjustment screw tightens securely, so I think there will be no problem using it, but since it has been stored for a long time, please consider it as a junk item. The black protrusions on the back (see photo) were sticky due to aging, so tape has been applied for protection. The carrying bag is faded, but it seems to be usable. Thank you. #ArchitectExam
