MOKUPEN Kyo's wooden shaft pens are handcrafted with care by me, a house construction engineer. The metal fittings are from Off Corporation in Japan. The name of the metal fitting this time is "Fun Line." The wooden shaft uses [Japanese oak]. It is thicker at the bottom for easy grip. Also, the carnauba wax used for finishing is derived from the leaves of the natural carnauba palm. It is characterized by its high hardness and melting point. It is much harder than beeswax, etc., and has a high melting point of 80°C to 87°C, so it is not sticky even at high temperatures. It has excellent gloss and becomes more lustrous the more it is polished. ◆I'm sorry, but since a customer who is purchasing in person is waiting, I will stop listing soon. Thank you for your understanding.

After that, the base is treated, and then carnauba wax (natural material) is applied and polished with friction heat to finish. [How to replace the refill] Pull the wooden shaft pen from the middle to both sides, and the clip side will come off. Then, there is a black part inside. You can remove the refill by turning that part.
