I found this while cleaning out my parents' house. It was haphazardly placed in a drawer, tangled with rubber bands that had melted and stuck to it (photos ⑤ and ⑥). The refill itself seems to be fine. It's a mystery why this was in a house with no connection to drafting, but I guess that's just how things are with my parents' place... This was likely sold for drafting purposes in the Showa era, and it's unclear if the product is still usable. However, I'd like to give it to someone who can use it, or to anyone who wants it. Please understand that this is a used item and has been stored at home for a long time before purchasing. There are no smokers or pets in my parents' house or my own. I will wrap it in cushioning material and take waterproof measures before shipping. I may also use recycled materials for packaging. Thank you for your understanding.
