Thank you for viewing. This is a high-quality glass pen manufactured by "Seifu Sugawara," a glass studio in Kitashirakawa, Kyoto. I purchased two different colors but didn't use this one. I'd like to sell it to someone who would appreciate it. The purchase price was 23,100 yen, so I think it's a great deal. 【Hard Glass Pen Seifu】 By making the diamond pattern on the grip thicker, the center of gravity is lowered, making it a pen that is easy to hold and write with. It is suitable for writing letters and drawing pictures. Recommended for everyone, regardless of gender. Among the Miyabi, Seifu, and Daimonji models, this one has a grip that is the middle thickness. ☆This is the most popular product. Color: Wakaba (Green) Size: Approximately 15mm in diameter x approximately 155mm in length Accessories: Velvet case, PILOT black ink, profile booklet I will ship via Yu-Pack Plus (free shipping). *Please note that the booklet will be bent in a U-shape for shipping.
