This is a custom fountain pen from Michal at Tamenuri Studio. The Aka Tamenuri Ishime urushi features shades of deep red and black with a stone like texture. This is a technique that I've never seen replicated on any other fountain pen.

The Bock nib is made of 14k gold and features a medium point. It has their logo engraved on it.

Overall, the pen is in excellent condition and has no issues. I had only used it a couple of times and it has been sitting in my display box since. Originally, I paid about $900 for it.

Please let me know if you have any questions. I'll be posting some other beautiful fountain pens from my personal collection over the next couple of weeks, so please feel free to check out my other listings!
