DRAPAS Slope Ruler 20cm This is a slope ruler used for drafting, etc. I bought it for a certification exam, but no longer need it, so I am selling it as a new, unused item. (See the first photo for the contents) (The box was opened only once for the photos) I wish those taking certification exams the best of luck in passing! Condition: New, unused Retail price: 3960 yen (tax included) Thank you for looking.
