SAILOR Sailor Ballpoint Pen (Knock Type) ☆ Unused

I don't remember exactly, but I think I bought this ballpoint pen about 30 years ago.
I kept it in a pen case without using it.
Currently, the ink doesn't work, probably because it's old.
It cost 2500 yen at the time.
The weight is about 20g, but please forgive any slight errors.
The price sticker from that time is still attached.
There's a mark where I tried to remove it once (photo 13).
I'm not familiar with ballpoint pens, but it says "替え芯 18-0300" (refill 18-0300), although I don't know if it's still sold.
I will give it to someone who can use it.

Although it's unused, it's been stored at home for a long time, so I think there is some deterioration over time.
There are no noticeable scratches or stains, but I think there may be some minor scratches.
Please consider this only if you understand.

I will ship it in simple packaging via Yu-Packet Post Mini.
Please refrain from price negotiations.

I have a pet (1 cat) and I don't smoke.
