This is Paraglass's glass pen, the "Royal Glass Pen." It has only been test-written at the store where it was purchased, and has been displayed in a glass case since purchase, so it is unused. This is a beautiful glass pen with a wave-like twisted pattern and a blue and purple gradation. I haven't been able to use it because I felt it would be a waste, so I would like to pass it on to someone who will use it. Length: Approximately 13cm Nib width: I believe it is fine to medium.
