Purchased in 2017 from Nagasawa Stationery Center. It's a Platinum fountain pen, "Shine Crystal" with an M (Medium) nib. It's not just a clear body; the barrel has facets that catch the light at different angles, which is where the "Shine Crystal" name comes from. The nib also has an original Nagasawa design, and the intricate engraving satisfies the desire to own something special. It was inked once for a test write and then stored in a dark place. I am selling it now to release part of my collection.
