This was my first Danitrio. I haven’t seen another pen similar to it, so perhaps it never passed the prototype stage. The entire pen is ebonite, except the feed. The barrel features sterling silver inserts: one engraved with a phoenix, the other with a dragon.
I’ve had it a couple of years, and it shows. It’s scuffed in places, and it used to be shinier.

It’s big, but not heavy. The girth of the barrel makes it comfortable to grip. I do hold my pen in an unusual way, with my hand higher on the barrel and my thumb hiding under my forefinger, so this observation might not hold true for others.

It came with a flexible extra-fine nib, originally. I had it replaced with a flexible stub.

The ink is J. Herbin’s Gris Nuage, and the writing sample is on Rhodia paper.
