Kiyokaze Suga Glass Pen Glass Studio Homura This is a hard glass pen by Kiyokaze Suga of Glass Studio Homura. I purchased it over 10 years ago from a studio in Kyoto. The color is green, and the shape is a wide diamond-patterned form, like a smaller version of the Kamo flow, making it a rare item that is probably not available elsewhere. It is new and unused, as it was kept for display rather than practical use.
