I've brought this out from my parents' house. It's been stored indoors for at least 20 years. It's old and probably not practical to use, but I thought it was a shame to throw it away, so I'm listing it. It's about 80mm long and weighs 6g. As a general rule, the packaging will be simple, and I will reuse packaging materials such as envelopes, so I appreciate your understanding. I will also combine this with other items for sale. Most of the price is for shipping and fees, so if you combine multiple items within the weight and size limits, I think I can keep the price at the same 360 yen.
