"Penxo" is a mechanical pencil that uses a 2mm lead. Since no mechanical parts such as knock buttons and springs are used, it is a writing tool that can be used for a lifetime without breaking down.

Aircraft class aluminum is used for the body. Manufactured by precision carving single block aluminum. The design pays homage to the pencils that have been used for many years.

The structure is very simple, with the aluminum body sandwiching the core. When centering, instead of clicking the button like a normal mechanical pencil, use your thumb to press the gap in the center of the "Penxo". Then, the force to pinch the core weakens, and the core comes out due to gravity. It's so simple that I hesitate to call it a mechanism.

Can such a simple product be called a product? Some people may be starting to wonder. However, it seems that the goodness of "Penxo" lies in the details. For example, the gap in the center is said to be shaped to be optimal for adjusting the protrusion of the core with your thumb.

We are also focusing on design. "Penxo" is a mechanical pencil that can be used semi-permanently with almost no mechanical moving parts. It was designed with the aim of creating an easy-to-use and timeless form on the assumption that it will be used for a long period of time.

"Penxo" may be called a pencil made of aluminum rather than a mechanical pencil. Until now, pencils have been throwing away the wood that is held by hand in order to use a single core. "Penxo" is a pencil made by changing the wood part to aluminum so that it can be used many times. In a sense, it may be an eco-friendly product.
