I'm selling this because I don't use it much. I've only used it for test writing. The line width is medium to medium-fine when using a lot of ink. With less ink, it's medium-fine to fine. The nib is long, so please adjust the ink to write. I've barely used it, just for test writing, and I don't have the box, so it's just the pen itself. Please understand. I've stored it carefully, but it's a used item, so please refrain from purchasing if you are concerned about minor details. Since I don't have the box, I'll mark it as having some scratches and dirt. This glass pen by Kawanishi is a great item, so please consider it. It will be shipped via Yu-Packet Post. I will pack it carefully.
