This is a glass pen purchased at Kitaichi Glass in Otaru. It was purchased over 15 years ago. It has been used a few times and has been wiped clean and stored in its box. The included ink is also old and I think it has deteriorated. It's best to buy new ink separately. I'm selling it because it's a waste for me to keep it. I will wrap the box in bubble wrap, put it in a bag, and ship it via Rakuraku Mercari delivery.
