This item was used during my industrial high school days at the end of the Showa era. It's been over 30 years, but after being used for three years of high school classes, it was stored in a closet. I think it's in good condition for its age. The mechanical pencils are Pentel PG4 and PG5. The knocking mechanism has been confirmed to work. The HB lead is empty. Please judge the other conditions from the photos. Due to its age, we cannot accept any returns or complaints. There are traces of tape on the top of the case where drafting paper was attached to the drafting board. There are no problems with use.
