This is something I used a long time ago. I don't know the details, but I think it's been over 25 years. I received it somewhere, and something is printed on it, but it's mostly illegible. The metal parts are also quite deteriorated, but it can be used normally. My husband says it's more convenient because it's thinner than usual. Mechanical pencil Hexagonal Gold Length 13.5cm The condition is quite poor, so please understand before purchasing.
