Thank you for viewing. I purchased this from the official HlZEN website, but I am selling it because I have no opportunity to use it. This glass pen is made of porcelain, carefully coated with gold by artisans and fired. Great care is taken to ensure that the brilliance does not change during firing. The gold is applied while considering the balance between the triangular shape and the color of the glaze, giving a different impression depending on the viewing angle and how the light hits it, and it has a beauty that does not get old. The triangular design provides a firm fit when held in the hand, improving ease of writing. It is also visually beautiful and, unlike other common round pens, has a unique personality. ■ Kiln Touetsu Gama A 14th generation Arita-yaki kiln that began with the Hirado Han kiln (Mikawachi-yaki). We aim to create "monozukuri" (craftsmanship) and "dougu-zukuri" (tool making) that will be loved for a long time. We are good at making things stand out with glazes and designs, and the vessels using kiln-changed crystal glaze, where the crystals appear differently on each piece, are especially popular. ■ Size Overall: Approximately 170mm Porcelain part: Approximately 150mm ■ Materials Pen shaft: Porcelain (gold) Pen tip: Glass ■ Care/Handling Precautions It is delicately made.
