Platinum mechanical pencil made by Platinum. Purchased around 1970. This item is from the time when 0.5mm lead mechanical pencils began to become popular. I used it for a while after purchasing it, but eventually stopped using it and it was stored for a long time. The lead advances without any problems and is usable. The eraser is worn. There are scratches. This is a very valuable item from 50 years ago, when 0.5mm lead mechanical pencils were just starting to become popular. It evokes the Showa era, so how about adding it to your collection? Price reduced.
