A decorative key of impactful size ⭐︎ How about it for a retro collection? It seems to be a commemorative item for Coming of Age Day. According to the paper, which looks like an instruction manual, it can be used as a knocker, decoration, and bottle opener! I think it's a rare item ⭐︎ It weighs about 374g and is a bit heavy. (The paint part in the photo has the place name on it, so I hid it.) ※ Because the outer box has deteriorated and cannot be mailed, the main body will be wrapped in bubble wrap and packed and shipped. The instruction manual will also be enclosed. ※ Please purchase only if you understand that this is a long-term home storage item and a used item. m(._.)m ※ Please feel free to ask any questions in the comments section ⭐︎ Thank you for your consideration.
