This is a sharp pencil made from stabilized tamo wood. The lead diameter is 0.3mm, but it is compatible with Pentel Stein leads, and you can change it to 0.5mm by purchasing commercially available leads. I bought it, but it has been sitting in my desk, so I am offering it for sale to someone who will use it. There is no step between the wooden shaft and the metal fittings, and it is a masterpiece made with great care. The pen itself has a low center of gravity and is easy to handle, allowing for enjoyable writing while feeling the satisfying feedback. I am sorry, but I am not considering lowering the price. Thank you for your understanding.
